I will provide the failing config.log as an attachment.
Created attachment 82975 [details] The log from the failing ./configure ebuild compile did a: ./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-gtk-doc --build=i686-pc-linux-gnu

The following configure-test makes configure exit: /usr/bin/pkg-config --atleast-pkgconfig-version 0.9.0
Correction: After a more thorough examination, I detected that actually only the following configure test fails: /usr/bin/pkg-config --exists libgnomeui-2.0 gtk+-2.0
When I searched for the missing "libgnomeui-2.0", I noticed it is a component of ebuild gnome-base/libgnomeui wbich is not installed on my system! Seems there must be something screwed up with the dependency information of the truevision ebuild!
In order to get the missing library, an emerge --oneshot gnome-base/libgnomeui does the job. I therefore conclude that the ebuild which is used by my profile (libgnomeui-2.12.0.ebuild) misses the following RDEPEND entry: >=gnome-base/libgnomeui-2
Added missing dependency in cvs, thanks! Note that it should also go in DEPEND, as it is necessary for compilation. DEPEND -> needed to compile RDEPEND -> needed to run Cheers
