[9fans] cleaning up gentoo plan9port ebuild

[EBo]

While working on merging and cleaning up the 3 or 4 different portage ebuild
trees for plan9 and plan9port I ran into a number of things which I need
clarified:

* Gentoo's plan9port report's the license as MIT, yet the LICENSE file says it
is Lucent-1.02. Which is correct?

* Gentoo's plan9port also sets DEPEND="x11-apps/xauth".  Is xauth a build or
runtime dependency?

* Am I correct in my understanding that the only two things that the install
configuration ("${PLAN9}/INSTALL -c") do is change the hardwired
/usr/local/plan9 paths, and build the documentation in $PLAN9/dist?

* I've built an updated live ebuild which works directly from the plan9port
mercurial tree.  Is there enough interest to request that this be added to
gentoo portage?

Thanks

As p9p uses a lot of code from Plan 9, I would suspect that the correct license
is Lucent-whatever.

I added
http://aur.archlinux.org/packages/plan9us-hg/plan9us-hg/README.too to an
AUR http://aur.archlinux.org/packages.php?ID=32983 for ArchLinux, we
build from mercurial repo.

How about adding a slightly re-phrased REAME.too as follows:

"The bulk of this software is derived from Plan 9 and is thus
distributed under the Lucent Public License, Version 1.02, reproduced
below. There are a few exceptions: libutf, libfmt, and libregexp are
distributed under simpler BSD-like boilerplates.  See the LICENSE files
in those directories.  There are other exceptions, also marked with
LICENSE files in their directories or marked at the top of the file. The
bitmap fonts in the font/luc, font/lucm, font/lucsans, and font/pelm
directory are copyright B&H Inc. and distributed under more restricted
terms under agreement with B&H.  See the NOTICE file in those directories.

Most of the COPYRIGHT, LICENSE, NOTICE and, or README informative files
are installed, but in /usr/local/plan9/unix or $PLAN9/unix directory."

I think it would be a runtime dependency, xauth pulls in all the X11
libraries so you can X forward the GUIs from a headless machine. On the
other hand, most of my binaries seem to be statically linked, so I'm not
sure.

I would like a live ebuild in portage, or at least an updated version of
the tree. I have a live ebuild that I wrote a while back already, but it
has a few bugs. There's a related gentoo bug:

i think it's neither.  xauth is an application.  and the x libraries are not staticly linked:

; ldd sam
	linux-vdso.so.1 =>  (0x00007fff9d4a3000)
	libm.so.6 => /lib/libm.so.6 (0x00007ff821485000)
	libutil.so.1 => /lib/libutil.so.1 (0x00007ff821282000)
	libpthread.so.0 => /lib/libpthread.so.0 (0x00007ff821067000)
	libc.so.6 => /lib/libc.so.6 (0x00007ff820d18000)
	/lib64/ld-linux-x86-64.so.2 (0x00007ff821706000)

I had fixed it as:

DEPEND="x11-apps/xauth"
RDEPEND="${DEPEND}"

which appeased the reviewers, and seems to be the proper fix.

Your ebuild is the one I started from.  Thanks!  While they had me tweak a
bunch of stuff to pass Sunrise review, the only real problem is that
plan9port.tgz is updated on a regular basis and the ebuild expects any source
to be static and pass a MD5 check (IIRC) unless it is specifically set up for
CVS, SVN, Mecurial, etc.  This caused the ebuild to fail its check the next
time plan9port.tgz was updated.  I've since rewritten it for mecurial.  There
is still an issue with the "mv * "${D}/${PLAN9}", but there are issues with
using "doins -r" as it strips the executable bit off all files installed, and
"dobin" sets everything to executable...

I'll post a reply to bugs.gentoo and make a point to sent it to you when I
finish the Sunrise review of my recent changes.

OK.  I dug a little deeper and found that rio uses x11-libs/libX11 and
x11-libs/libXext as build dependencies.  These I think are the correct ones to
use and not xauth.  This does raise the issue then if the gentoo ebuilds
should conditionally use X and not build rio if you do not want rio on a
non-gui system.  That will of course be an issue for a program specific ebuild
system and not for plan9port.

here's the full list of dynamic libraries used on
a random gentoo box i tried:

; cd $PLAN9/bin
;>[2=]ldd `{file `{find .}|grep 'ELF.* shared'|sed 's/:.*//'}|grep -v :|
  sed 's/=>.*//'|grep -v /lib64/ld-linux-x86|sort|uniq
	libX11.so.6
	libXau.so.6
	libXdmcp.so.6
	libXext.so.6
	libc.so.6
	libdl.so.2
	libm.so.6
	libpthread.so.0
	libresolv.so.2
	libutil.so.1
	libxcb.so.1
	linux-vdso.so.1
