I had the same problem when I tried to build/install pycrypto on OS X 10.6.
It seems that gcc-4.2 doesn't support -Wno-long-double anymore (well not
the apple built gcc-4.2).  It is available in gcc-4.0 (and probably
earlier versions).

My 'work around' was to do the following.
    $ export CC=gcc-4.0
    $ ### do my build (e.g. python setup.py install)
    $ unset CC

Check which versions you have installed with:
    $ ls -l /usr/bin/gcc*

I also had to install the 10.4u SDK from the Apple install DVDs, but I
think that was some pycrypto constraint.

Cheers, Brendan.
