[Crypt::SSLeay] Prompting for PKCS12 password?

Hi,

It seems that (atleast with pkcs12 files) Cypt:SSLeay will only read
my client cert if the password for the crypted key is in my
$ENV{HTTPS_PKCS12_PASSWORD}.

I'm dealing with this through the RT (request tracker ticketing
system) CLI, so perhaps there's something in that perl code that's
mucking with things.

I'd expect the library to prompt the user for the password if the
environment variable isn't set, but this doesn't seem to be
happening.  Obviously I can modify the client to handle this, but is
that really necessary?

Thanks,
-Jon
