The output from cygcheck explains your "libpython2.2.dll could not be
found" problem.

Actually, you could get rid of the cygz.dll dependency by linking with
zlib statically.  Ditto for libpython2.2.dll once I support Cygwin
Python with a static core (which is dependent on Cygwin ld supporting
exports from a .exe).  However, the cygwin1.dll dependency cannot be
eliminated unless you use Mingw.

OK.  I was just trying to understand the issues involved.

Good.

Yup.  Once again, the cygcheck output confirmed it:

                  ^^^^^^^^^^^
