Hi, Jeffrey,

Yes, I use Python 2.4.3 built this way.  I did not have any significant 
troubles building Python on my 10.4 system.  My configuration step was a 
little different from yours, but basically I just checked out the 2.4.3 
source from Subversion, and this is how I configured it:

 env CFLAGS="-I/usr/local/include 
-I/Library/Frameworks/Tk.framework/Headers" \
 LDFLAGS="-L/usr/local/lib" \
 configure --enable-framework --enable-shared

I included /usr/local/include and /usr/local/lib so that the build could 
use the version of GNU readline I installed via Darwin ports.  The Tk 
headers allow pythonw to build properly. 

Having configured, I built and installed via:

  sudo make frameworkinstall

I hope this may be helpful to you.
