If you're on a 64bit capable OS X host the configure script assumes
that you want to compile a 64bit binary. Unfortunately macports
doesn't (at least not easily) compile 64 bit binaries or fat binaries.
So if you're using the macports version of python that won't work for
a 64bit compile. However, the version of Python that comes with 10.5
has libraries that are fat (32 & 64 bit), so you can compile a 64 bit
binary. The speed of the 64 bit m5 binaries is drastic enough that I
deal with the hassle, but perhaps we need a more elegant solution.

Using the normal SConstruct, it is unable to find my Python.h file

Looking into the SConstruct, I found that in b5 some 64bit
compilation option was added ("-arch x86_64"). When I comment out
the appends done to the environment variables (starting at line
396), I am once again able to build the simulator without error.
I'm not familiar enough with SCons to know if there is a bug in this
code, but this may be an issue.
Not sure if it matters but I'm using OSX 10.5 on a core 2 duo.
