Bugzilla Bug 101465

media-libs/allegro-4.0.3 fails when emerged with tetex use flag on (goes ok
without that flag). 

Error:
cd docs && texi2dvi -c texi/allegro.texi && cd ..
This is e-TeX, Version 3.141592-2.2 (Web2C 7.5.4)
---! /var/lib/texmf/web2c/etex.fmt was written by pdfetex
(Fatal format file error; I'm stymied)
/usr/bin/texi2dvi: texinfo.tex appears to be broken, quitting.
make: *** [docs/allegro.dvi] Error 1

tetex version: 3.0-r2


Reproducible: Always
Steps to Reproduce:
USE="tetex" emerge allegro

let's hear from the text-markup group please.

I have the same issue with emerging allegro (4.1.18 though) when using
tetex-3.0-*.  Running texi2dvi on any .texi file on my system fails with the
same error.  Running etex on any .tex file also gives the etex.fmt error.
However, downgrading to tetex-2.* allows texi2dvi to work here also.
It looks a bit like bug 97239.

I've tried using fmtutil-sys --edit to change the etex format to use the etex
engine (as opposed to pdfetex) and then running fmtutil-sys --all to recreate
the /var/lib/texmf/web2c/*fmt files, but I get the same error.  (Still the
"written by pdfetex" bit, even though it's set to use the etex engine.  I've now
run out of things to try for this.

same here

Same problem here with media-libs/allegro-4.2.0.

This is a known problem with tetex-3 and etex... We are currently looking at
how
to solve it but so far didn't succeed.
Merging with tetex-2 or disabling the doc/tetex USE flag seem to be the only
options available now.

Digging through the tetex mailing-lists, I found this "fix". It worked for me
on
another package, so perhaps can it help you too (it's really dirty and not a
real fix, though) :

cd /usr/bin
mv etex _etex
ln -s pdfetex etex


If you try it, please report success or failure.

The fix mentioned in #6 works for me. But does it create problems somewhere
else?
