Where did you get this source from, I don't see "symverscript" in any of our current code release trains. Also I suspect your patch is wrong anyway, it looks merely like a default make target mistake (by being the first target parsed) and not something you'd want to remove the target for.

Look at m-i. I'm not saying the patch is good, just that it fixes the build. :)

Ahh I'm not used to people reporting bugs against inbound in non-default (in mozilla-continuous integration) configurations, so didn't catch this. This is a regression/problem in http://hg.mozilla.org/integration/mozilla-inbound/rev/75e0d521bc2b - Bug 809430 - Add symbol-versions to libxul and libmozjs for linux. r=glandium For a surprise to me this bustage was even with a build-system peer reviewing ;-) so I'll hand over to the gentoo guy and glandium to fix.

I backed out https://hg.mozilla.org/integration/mozilla-inbound/rev/75e0d521bc2b to fix this. Clearly none of us have any idea what the right fix is, best to punt back to the original author. :-)

Ah, the rule is too high in the file and is picked as default.

I thought bug 777379 should have prevented this sort of bustage?
