Installing PIL on OS X Snow Leopard w/Xcode4 (no PPC support)

Xcode4 dropped PPC support, so when I try building PIL, it throws hate:

I ran that first line, manually, and removed the -arch ppc option and it didn't report back with any errors, but rerunning the build process ignores this manual attempt. `gcc-4.0 also does not exist, I symlinked it to gcc-4.2.

I could go ahead and install Xcode3 and then 4, but I want to muck up my fresh install.

Is there anyway to tell PIL to not compile for PPC? I did a grep across the distribution but i did not find a single mention of PPC. Any ideas?

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 -s

then ARCHFLAGS="-arch i386 -arch x86_64" pip install PIL to 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)!

Just to help others... I had to use ARCHFLAGS="-arch x86_64" before building imaging with my Snow Leopard/XCode 4 system i.e. having "-arch i386" in their stopped it working for me.
