Installing PIL on OS X Snow Leopard w/Xcode4 (no PPC support)
The solution has nothing to do with PIL but rather setting gcc's ARCHFLAGS:
ARCHFLAGS="-arch i386 -arch x86_64" sudo pip install PIL
ARCHFLAGS doesn't seem to get passed into sudo. I had to do
sudo -sthen ARCHFLAGS="-arch i386 -arch x86_64" pip install PILto make it work.
A better way to solve this issue, in my opinion, would be to edit your ~/.profile or /etc/bashrc and add the line:
export ARCHFLAGS="-arch i386 -arch x86_64"Will save messing around with any future installations (I've just had to do this for installing lots of Perl modules in CPAN)!
