On another box I have less optimizations but it fails too

Please use "New -> Gentoo Linux -> Component: Ebuilds" in future.
Infrastructure
is not the correct addressee.

Looks like we need to add an -L to path containing libmopac in the workdir.

Could you try that manually and see whether it works?

When I go to /var/tmp/portage/mopac7-1.00/work/mopac7-1.00 and write make (or 
make clean; make) it compiles cleanly. I compared the output and it seems that 
the ebuild did not link the library before trying to link the executable. 
Therefore the library libmopac7 is simply not there, when it wants to link 
against it. The manual make is doing it right, but I have no idea why.

That's odd, because the ebuild does nothing weird in the actual make process.

    emake || die "emake failed"

And emake is simply:

${MAKE:-make} ${MAKEOPTS} ${EXTRA_EMAKE} "$@"

Do you have MAKEOPTS set to something greater than 1? If so, does reducing it to
1 fix the build?

Yes that did it. I didn't know that it can cause problems (But now its 
obvious ;-). I had -j2 as recommend by the Gentoo Handbook: 
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=5 

Thanks, Mathias 

This fixed it for me also...
Tks

It can occasionally cause problems when you're trying to build interdependent
things at the same time. The handbook recommends it because it usually works,
and when it doesn't we usually have a fix in the ebuild.

I've committed a fix for this. It should hit mirrors in an hour or so.

Thanks for testing!
