System: FreeBSD mastodon.meroh.net 10.0-CURRENT FreeBSD 10.0-CURRENT #5 r255488M: Sun Sep 15 11:17:08 EDT 2013 jmmv@mastodon.meroh.net:/usr/obj/usr/src/sys/GENERIC64 powerpc
>Description:
The ports system defaults to using gcc46 or above when USE_GCC is set
in a package. However, gcc46 does not support powerpc64 so this
default is broken in a powerpc64 host.
The solution to this problem is one of:
1) Fix gcc46 in powerpc64. Dunno how hard or worthwhile that is.
2) Bump the default to 4.7 for all platforms. Things can break and
if the default is still 4.6, there probably is some reason.
3) Bump the default to 4.7 in powerpc64 only. Easy to do, but not
consistent across platforms.
>How-To-Repeat:
Attempt to build www/firefox in a powerpc64 host. See the build
abort early due to gcc46 not supporting this platform.
>Fix:
I think option 3 above is the easiest at the moment and can be
achieved with:
