I don't see a need for registering anything. You should
just be able to explicitly say what tool to use for each
stage of the process.

I envisage something like this:

   from distutils import Extension, CCompile
   from pyrex.distutils import PyrexCompile

   foo_ext = Extension("foo",

Here Extension, CCompile and PyrexCompile are constructors
for dependency graph nodes. Their responsibilities are:

   Extension -- takes compiled object files and libraries
     and links them into a Python extension.

   CCompile -- takes C source files and turns them into
     object files.

   PyrexCompile -- takes Pyrex source files and turns
     them into C source files.

They would of course also take other relevant arguments
such as compiler flags, search paths, etc.
