Recent version 0.12 adds a configure time dependency on Crypt::OpenSSL::Guess, however it declares it in the Makefile.PL as a build time dependency. Therefore if your system doesn't already have ::Guess installed when it tries to run the Makefile.PL it will fail. This should hopefully be easily correctable changing the Makefile.PL to list that dependency as configure_requires.
Thank you.
