[GRASS-dev] grass + matplotlib on mac osx snow leopard

[William Kyngesburye]

I haven't built matplotlib before, but it looks like it linked FreeType statically into ft2font.so.

You normally get an error about a missing architecture if that's the problem.  But in the case of a statically linked library, maybe ft2font.so (matplotlib) is the right arch, but the linked freetype was not.  Because of the way Python modules are linked, you don't get link errors so you don't know until you run it.

Try checking the archs on the freetype used when compiling matplotlib, and check the archs on ft2font.so.  They should have the same archs.

[Marvin]  You think you have problems?  What are you supposed to do if you ARE a maniacally depressed robot?  No, don't try and answer, I'm 50,000 times more intelligent than you and even I don't know the answer...
