well, ldd here spits out some more, libjpeg and libpng amongst it as
well as libz and libm. Just exchanged all calls for libxy.a to -lxy in
the Makefile.

Well, they hopefully are taken care of in the Makefile of Mosaic, so i
actually don't care too much about them.

Well, i haven't dug that deep into Mosaic either, but judging from the
error message i got at least for libpng it's the fact that they're
using some function that's declared internal since version 0.95 (about
1998 i think). After changing the function call to the "new" one it
compiled fine. By tweaking the Makefile i coaxed it into including
libjpeg dynamically as well, libgif i haven't seen though.
So i might just caused the breaking by that. Dunno.

Well, here it is a fairly up-to-date Gentoo on PPC. And i believe all
dependencies are fulfilled (unless there are version issues i didn't
notice), but i don't know for sure.

Read about that one somewhere, but didn't need to apparently.

Probably enough. Given the nature of gentoo, there is no such thing
there as development packages here.

Just compiling gdb as we speak to check Camerons suggestion.
