I am attempting to install ossl on Windows XP with MinGW/Cygwin
I already have openssl installed. I get the following error:

$ ruby extconf.rb --with-openssl-dir=/cygdrive/c/apps/openssl
checking for strptime()... no
checking for openssl/ssl.h... no

Does anyone know where strptime should be defined?

Any tips on installing ossl on windows are appreciated.
