Let's go back to your original problem, which, if I understand
correctly, was trying to get going with Python 3 and gmpy on OS X 10.6.
(Sorry I was away over the holidays and didn't get a chance to respond
to your original postings at the time.) I believe the problems you
originally encountered with installing gmpy were all due to a couple of
problems with building C extension modules on 10.6 when using the
current 3.1.1 OS X python.org. Unfortunately, 3.1.1 was released before
10.6 was so there are a couple of important fixes that haven't yet been
released for 3.1 (but are in the 2.6.4 installer which was released
after 10.6 came out). Fortunately, though, there are simple workarounds
for the problems. Keep in mind, though, that, at the moment, the
python.org installers for OS X are 32-bit only; that will change in the
future but if you do need a 64-bit Python 3 you'll need to stick to
other solutions like MacPorts for the time being.
First, make sure the gmp library you've installed has 32-bit support.
If you installed it using MacPorts, check with the file command:
$ file /opt/local/lib/libgmp.dylib
/opt/local/lib/libgmp.dylib: Mach-O universal binary with 2 architectures
/opt/local/lib/libgmp.dylib (for architecture i386): Mach-O dynamically
linked shared library i386
/opt/local/lib/libgmp.dylib (for architecture x86_64): Mach-O 64-bit
dynamically linked shared library x86_64
If it doesn't have an i386 variant, reinstall the gmp library from
MacPorts:
$ sudo port selfupdate # make sure MacPorts is up-to-date
$ sudo port clean gmp
$ sudo port install gmp +universal # install 32-/64-bit variants
Second, you need to install the MacOSX10.4u SDK because the current
python.org pythons are built with it. That SDK is included in the Snow
Leopard Xcode installer package but it is not installed by default.
There should be an Xcode.mpkg somewhere, perhaps on your hard disk if
your system came with Snow Leopard factory-installed or perhaps on a
restore DVD. If not, it's on the retail Snow Leopard DVD and can be
downloaded from the Apple Developer site. After launching the Xcode
installer, just select and install the "Mac OS 10.4 Support" package
from the Custom Install menu.
Third, you need to tell Distutils to use the older gcc-4.0 instead of
the gcc-4.2 which is now the default on 10.6.
$ cd /path/to/gmpy-1.11rc1
$ export CC=/usr/bin/gcc-4.0
$ /usr/local/bin/python3.1 setup.py install
...
$ /usr/local/bin/python3.1 test3/gmpy_test.py
