[9fans] plan9ports won't compile: undefined ref to getcallerpc

[Derek Davis <derek.davis@gmail.com>]

I've been trying to compile plan9port in linux simply so that I can
use Acme.  However, whenever I run the install script, it will go for
a while but quit with errors when running '9l -o o.9p 9p.o...'.  All
the shown errors are in the file fdwait.c, and are due to undefined
reference to getcallerpc.  I opened fdwait.c and it includes libc.h,
which defines getcallerpc, so I am not sure what is causing the error.
 Google searches turned up nothing, and I could find nothing in the
list archives about this.  Have you seen this problem before, and do
you know what might be causing it?  I am building on a Gentoo system
using gcc 3.3.4-r1.

Thanks in advance.
