SSL on Windows?

I need to do this too..
I DL M2Crypto windows binary release (0.4 because 0.5 release RSN)
now I only need to do a SSL client (to hit an existing server). I
started
playing with the demos.. (specifically echo.py)
I keep getting PRNG not seeded. (see traceback below)
The line that apparently seeds PRNG is this:
Rand.load_file('../randpool.dat', -1)
I can change it so that it points to a different file and then the
script will
make the SSL connection and get the web page but it causes an invalid
page fault
in python.dll

My ultimate destination is to make a script that will do a https post to
a URL
and get a response.. 
I can get a perl library to do this.. but.. I wanna use python =)
