I agree. There are so many variations of the dependencies, that fink is
quite good. When trying to build qt for x11 for example, it is a pain to
figure out how to build for Qt for x11. Many of the source packages turned
out to have problems. I suspect this is because Qt-X11 is rarely used on
MacOSX. Then there is the whole 32bit/64bit thing. The only problem I had
with fink was with installing wxPython, since libgnomecanvas2 is broken.
On a different note, I've got the geom and mesh libs to compile. Is there
way to see the results visualised as they happen?
E.g., Level2/PAF/paf_smesh.py runs in the console, but only when it's done
does it display the result, then blocks on my_context.start_display(). Is
there a way to make that non-blocking? Or interactive as in the videos?
Thanks!
