Moodle Networking: cannot find openssl.cnf so networking fails.

When going through the Site Administration tree in the latest CVS and with server Debug messages set to normal, most items of the Networking branch give several warnings of the form below that are within the function mnet_generate_keypair. We don't use this form of networking yet, so I am unable to fully understand the problem, but it appears that the keypair is not being generated. And the admin block should not be giving warnings under normal initial install situations. There have been several changes to these files in the past 5 days, so perhaps an issue got introduced.

Here are the messages:
