improving support for 8-bit displays a few years ago when people started wanting
to use it on things like the OLPC and eInk displays (with 64 and 16 colours,
respectively).
The problem is that the cairo port pulls in gobject-introspection that in the
end tries to pull in python 2.7. But this python version doesn't build on 32Bit
sparc, at least not with gcc4.2.1. IIRC, other *BSD suffer the same problem.
Python 3.X is also in the ports, but the gobject-introspection doesn't build
with that :(

sure, I can prepare things for you. I could also give you access to a
SparcStation 5. Its a little bit faster, 170MHz instead of 110, and 196MB RAM
instead of 64. Send me your ssh public key, and I'll prepare it for you.
