python in windows

I have a small remark concerning msvc 7.0 and the pre-compiled version of
python in windows.
Recently I tried to compile the source-code for a library named PyMat, a
link between python and matlab.
I wanted to use this library in windows with python2.3. I tried to compile
with microsoft visual c++ 7.0 ( NET ) and disutils.
The pre-compiled version of python 2.3 is however compiled with msvc 6.0...
This seemed to be a problem for disutils.
I recieved following error/ following exception is raised:
"error: Python was built with version 6 of Visual Studio, and extensions
need to be built with the same version of the compiler, but it isn't
Thx to google, I found the following sollution:
In $python_root$/lib/disutils/msvccompiler.py you have to comment out some
lines (approx: line 214)
## if len (self.__paths) == 0:
## raise DistutilsPlatformError, \
## ("Python was built with version %s of Visual Studio, "
## "and extensions need to be built with the same "
## "version of the compiler, but it isn't installed."
% self.__version)The compiled library works correct.
The library compiled and seems to work correct!
Now my question is: is it absolutely necessary to compile everything with
the same msvc as python is compiled with?
If not, is the line in msvccompiler.py absolutely necessary? Could this be
replaced with a warning, instead of raising an exception? Simply aborting
completely the compilation proces seems kind of drastic.
greetz and thx for reading so far
ps. I presume this problem still is present in python 2.4,
because msvccompiler.py still contains the conflicting lines in the
