To build and install a C extension module included with MMTK, Python is looking for the C compiler it was built with. For OS X 10.6 (Snow Leopard), the least trouble-prone way to supply this is to install Xcode 3.2.6, the most recent (and last) version of Xcode 3. If you don't already have an installer for it, you can download it for free (after free registration) from the Apple Developer Site. Make sure that the UNIX Development sub-package is selected to be installed.

If you have Xcode 4 for OS X 10.6 installed or some other C compiler, you might be able to successfully install the extension module by supplying a CC environment variable with the path to the compiler, for example:

export CC=/usr/bin/cc

You may also need to supply other variables that reference the compiler path, in particular, LDSHARED.
