# If you get an error message like the following:

# error: Setup script exited with error: Python was built with version 7.1 of Visual Studio, and extensions need to be built with the same version of the compiler, but it isn't installed.

# Then that probably means that you aren't using the the right
# compiler.  In that case, try creating distutils configuration file
# (as described in http://docs.python.org/inst/config-syntax.html ),
# specifying which compiler to use.  For example, if you use either
# the cygwin gcc compiler with mingw support, or the MINGW compiler,
# then you can add the following lines to your .cfg file:
# [build]
# compiler=mingw32
