It looks like the compiler cannot find isinf, and possibly this patch is
guilty:
http://code.google.com/p/lilypond/issues/detail?id=4550
isinf is supposed to be defined in cmath (without scoping) which is
included by flower/include/offset.hh. And of course this works on most
platforms or we'd have gotten complaints already.
Now darwin-ppc is an obsolete platform and consequently our cross
compiler/library is likely not all that up-to-date. I fear this is
likely a compiler/library bug and it will likely be rather tough to
figure out an appropriate workaround when the only available test is
running GUB by a volunteer without much knowledge about either GUB's
internal workings or Darwin-PPC.
Would it be feasible to run on a version where the patch for issue 4550
has been reverted? We might cheat our way through in that manner (this
is not likely to have runtime effects) but short of a volunteer to
figure out what's going wrong here in detail, it might mean that maybe
it's time to retire Darwin-PPC. We can still bring it back in once
somebody volunteers to fix this and possibly future problems.

I applied Hosoda-San's patch and the problem moved to lookup.cc. Fixed that
and got a fail with another *.cc. It would seem the best fix would be for
someone with the skills in Unix command line to replace all instances of
isinf and isnan (any others?) with the std::isnan prefix?
It only takes a couple of minutes for the build to fail, so experimenting to
get rid of the bug is not too wearisome.
