[yt-users] Python Compilation Error while Installing Stable yt on OS X 10.10.3

[Britton Smith]

Hi Madison,

Just to follow up on this, I happened to have the exact same problem at
about the same time.  Following Nathan's suggestion, I did:
export CC=clang
export CXX=clang++

and removed the old installation and started the install script from
scratch.  This worked for me.
