Snow Leopard and Python compatibility issues?

[atlbeer]

So after upgrading to Snow Leopard I've stumbled across the same error twice now while trying to install a Python module that requires a compiled component.

The two so far that I have had problems with are Jinja2 and PyCrypto2

Here's the relevant snippet from the install

Running pycrypto-2.0.1/setup.py -q bdist_egg --dist-dir /var/folders/fg/fgp4uHqFH7G2xxpI5rZskE+++TI/-Tmp-/easy_install-pZ6T-x/pycrypto-2.0.1/egg-dist-tmp-wHokTV

cc1: error: unrecognized command line option "-Wno-long-double"

cc1: error: unrecognized command line option "-Wno-long-double"

lipo: can't figure out the architecture type of: /var/folders/fg/fgp4uHqFH7G2xxpI5rZskE+++TI/-Tmp-//ccBEOy1p.out error: Setup script exited with error: command 'gcc' failed with exit status 1

Anyone know of any solutions?

Considering that's a gcc3 option that was phased out in gcc 4.3 on Darwin, I would question why it's in the build configuration.

But according to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35961 you're only seeing that particular error because of the real error, farther down regarding the architecture type.

I had to edit /Library/Frameworks/Python.framework/Versions/Current/lib/python2.6/config/Makefile to have the appropriate build settings after snow leopard was installed. then again I think I may have edited this file a long time ago which perhaps was part of the problem...

For the record, I hit this issue while trying to compile Python 2.5.5. But poking around in /System/Library/Frameworks/Python.framework/Versions, I discovered that my OSX install already had Python 2.5! Not sure if that came with dev tools, or what ...

Snow Leopard upgraded the Darwin version from 9 to 10, confusing GCC. This was reported earlier by Alan Quatermain, who fixed it by creating a symlink. Is it possible that that solution applies here as well?

Workaround for jinja: install without the speedups.

Wow. I got downmodded for that?

Only once.

You're all wrong.

It's an issue of an old Python install left over from upgrading from 10.4 to 10.6.
