PyCrypto builds neither with MSVC nor MinGW

Hmm, I just tried that method, but the output I got was still:

and when I manually run vcvarsall (which is in PATH), I get the
aforementioned linker errors:

> Although I was able to specify an include directory for mpir.h with -Ic:\usr\include, I was not able specify a lib directory with -Lc:\usr\lib. It looks like setup.py does not honor the -L option. So I finally gave up and just copied the mpir.h file into my Python27\include directory and the mpir.lib file into my Python27\libs directory.
