SpiderMonkey won't compile on PPC and probably x86-64 (can't test that though) because of an undefined reference to VA_COPY Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 50903 [details] spidermonkey-1.5_rc6-va_copy-fix.patch
Created attachment 50905 [details] Ebuild patch
Needed to add: inherit eutils at the very beginning of the ebuild, but then it worked!!!! And it's on amd64 Please add "~amd64" to the KEYWORDS for dev-lang/spidermonkey-1.5_rc6-r1
Added to CVS. Thanks for providing the patch!
