After running into the error "Setup script exited with error: Unable
to find vcvarsall.bat" when trying to use easy_install / setuptools a
little digging showed that the MS compiler files in distutils only
support up to Studio 2008. Does anyone know if there is a timetable
for when Studio 2010 will be supported?

I am using python 2.6.5, but web searching seemed to show that 2.7 or
3.X didn't support it yet either.

You should use VS 2008 - the lack of distutils support is only the
first of a long list of issues if you want to use another compiler to
build python extensions. Unless you really know what you are doing,
you are better off with VS 2008,

Forgive my ignorance, but AFAIK mingw can be used to build extensions
for standard python distributions. After all, it's C we're talking here,
not C++. So I have difficulties imagining VS2010 is that much of a
problem. So - which problems you expect?

VS2010 uses a different C runtime DLL than VS2008 and Python 2.6, and I believe
this cannot be changed. This will cause errors for a variety of Python extension
modules. mingw can be retargeted to link against one of several different C
runtimes, including the one VS2008 uses.

Yes, mingw may be used - I assumed that the OP was interesting in MS compilers.
