Greetings, I've been working a few different 64 bit machines with a few different python installations. I'm trying to determine a foolproof way to see if when install_lib is run libraries are installed in a lib or lib64 directory. Here is what is the best that I've come up with so far, and it doesn't always work. import distutils.sysconfig libdir = distutils.sysconfig.get_python_lib() libdir.find('lib64') Has anyone else dealt with this, and if so, how did they handle it? Thanks, Matt Rodriguez
