The error message included the command about LDSHARE in it's final paragraph. I've included the error message at the end of this email, starting from the part where it appears to have run in to issues.

It looks like a copy and paste error.  Note the environment variable settings I suggested were:

$ export CC=clang
$ export LDSHARED='clang -bundle -undefined dynamic_lookup \
    -arch i386 -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -g'

But in the Distutils output I see:  "-arch i386 x86_64"
