While downgrading the x86 binaries for amd64 I ran into a unexpected error message: (realplay.bin:31998): Pango-WARNING **: No builtin or dynamically loaded modules were found. Pango will not work correctly. This probably means there was an error in the creation of: '/etc/pango/pango.modules' You should create this file by running pango-querymodules. The error message should be modified to fit the x86-binaries naming scheme. If someone is new to Gentoo or new to the x86 binaries he or she won't know how Gentoo handles this. So I believe it would be helpful to have a correct error message. However I admit that this isn't a big issue.
If you have problems w/ 20071214, reopen this bug. Nothing to fix with outdated ebuilds.
