[pyOpenSSL] DLL load failed.

[patrick flaherty]

Hello Jean-Paul,

As you can see below I copied ssleay32.a to c:\python25\Lib, however the 
build (link/ld) fails.

I think the key part might

-leay32

I don't know gcc in detail but my guess is that this statement makes the 
gcc link/ld look for libeay32.dll - not ssleay32.a
