Can I compare with someone?

Can I compare with someone?

[David Arnold]

All,

I've recently installed tetex 2.0.2. I am having difficulty with Metapost
and I am wondering if I have a good installation. If someone else out there
is running tetex 2.0.2, could you try the following on your system and tell
me if you get similar results. Also, if I'm making some sort of silly
mistake, please let me know.

I have a little file named junk.mp.

beginfig(1);
path p;
p:=fullcircle scaled 100pt;
draw p;
endfig;
end.

It compiles much as I expect.

[darnold@ps-114a-2k darnold]$ mpost junk
This is MetaPost, Version 0.641 (Web2C 7.4.5)
(junk.mp [1] )
1 output file written: junk.1
Transcript written on junk.log.

No problems. Now I add a line to junk.mp.

beginfig(1);
path p;
p:=fullcircle scaled 100pt;
draw p;
label(btex $x$ etex, center p);
endfig;
end.

Now, when I compile, texexec seems to be invoked. Is this what happens on
your systems? Is this correct behavior?

I now add another line to junk.mp. This is an attempt to get 10pt font size.

beginfig(1);
defaultscale:=10pt/fontsize defaultfont;
path p;
p:=fullcircle scaled 100pt;
draw p;
label(btex $x$ etex, center p);
endfig;
end.

But when I compile, I still get 12pt. And the culprit seems to be:

bodyfont       : 12pt rm is loaded

I tried the following workaround by editing junk.mp. But,

mpost junk

produces this error message:

! Undefined control sequence.
l.1 \documentclass
                  [10pt]{article}

So, I try:

mpost --tex=latex junk

But now my system tries to build cont-en.fmt. Toward the end, one message I
get is:

Sorry, I can't find the format `cont-en.fmt'; will try `context.fmt'.

But this doesn't make sense, as cont-en.efmt is already built.

I am at a loss at how to proceed. Is this a bug?

defaultfont/defaultscale only affect labels set by metapost
i.e. label("text",(0,0));
for the labels typeset by tex (btex ... etex) you can add to your
mp-file:

verbatimtex
\setupbodyfont[10pt]
etex;

It seems that somebody changed texmf.cnf, e.g. declaring here
something like:
TEX = context

or, worse, changed makempx script.
Anyway, tetex 2.0.2, as it is distributed is OK.

I've observed that some Linux distributions provide changed tetex
config files, not always in a happy way... 
I don't know how such situation could be cured, as packages are often
not signed. The notable example is still not updated tetex in 
the _current_ RedHat9.0. It is still tetex 1.0.7, but broken in many
parts.

Aha! I found this in my texmf.cnf.

% What MetaPost runs to make MPX files.  This is passed an option -troff
% if MP is in troff mode.  Set to `0' to disable this feature.
MPXCOMMAND = texexec --mptex
