I have verified that this package works for ppc64. Please add the ~ppc64 KEYWORDS to media-gfx/graphviz-1.10.

It does not work for me (gcc 3.4.1, full ppc64 toolchain), see attached build output.
I read your error log. In your environment, gcc links /usr/lib/libjpeg.a . However, in my environment, gcc links /usr/lib/libjpeg.so . (but, I use gcc 3.4.0) hmm... I think that this problem is related to bug#56469 and bug#56615. These bugs were closed recently.
Yep, bug#56615 it is, fixing it (and reemerging jpeg) solves the issue at hand. Successful build and working of graphviz hereby confirmed.
Thanks Yuta, Thanks Stefan!
stick a fork in it
