Having gone down that road myself, you may be interested in PyMake:

It is make implemented in Python. It isn't feature complete, but most of 
it is there. Mozilla uses it to build Firefox, specifically on Windows, 
where the new process overhead of regular make adds significant time to 
builds.

The built-in make functions are implemented as Python methods. And, 
there is even some logic to turn basic rules into in-line Python. Also, 
if your rule begins with a '%' it is converted into a Python function 
call instead of a shell invocation. If you change e.g. CC to '% 
mybuildsystem.compile' you can simply implement the function 'compile' 
in a 'mybuildsystem' module (on sys.path) which can capture the 
arguments, record executing times, etc. It's a pretty nifty backdoor.

If you have any questions, it is arguably off-topic for this list, so 
just ping me on IRC - I'm IndyGreg. Or, join #pymake on irc.mozilla.org 
(I'm gps there).
