[Qgis-developer] Mac Os X Snow Leopard and Qgis 1.7 - problems with opening python module for 32 bit architecture

[William Kyngesburye]

What I meant was that pygraphviz (or graphviz) probably uses a library that is not available in a 64bit version, so can't be made 64bit itself.  TclTk and wxPython are 2 such common GUI libraries.

... hmm, looks like graphviz has a tcltk part... but the libraries are all 64bit... so maybe it's the pygraphviz compilation that is not working 64bit (I didn't see any Mac download for it).

The equator is so long, it could encircle the earth completely once.
