installing matplotlib in MacOs 10.6.8.

[Alex Ter-Sarkissov]

thanks Ned,

that's quite weird: if I run python2.7-32 in terminal, it works like you
said, but when I add it as an interpreter in Eclipse, matplotlib.pyplot
doesn't get imported for some reason. Even more strange, either way
platform.architecture() reports 64-bit. What's wrong here?

cheers,

Alex
