[Yt-dev] Mac OS X Lion

[gso at physics.ucsd.edu]

I've tried to use the compilers in gcc 4.5 and 4.6 (installed via
macports) to install YT, but they fail during the numpy installation
(errors below).  So I went with the Xcode compilers in version 4.1 from
apple's developer's website and that worked on this macbook air with Lion
pre installed.

Looks like the compilers didn't recognize the option "-faltivec"
