[Pythonmac-SIG] compiling PIL on OSX10.5

[Ronald Oussoren]

Which version of python are you using? The Python.org installer builds  
extensions using the 10.4 SDK to ensure that extensions will actually  
run on that platform.

BTW. What I don't undestand is why building PIL tries to link libcrypto.

Do you have a libcrypto dylib in /usr/local/lib? If so, what is the  
output of the file command on that? (file /usr/local/lib/libcrypto*).  
It seems that the libcrypto that's linked into the extension is PPC- 
only, while distutils tries to build a 32-bit universal binary.
