mail/mpop fails with option OpenSSL but builds with gnutls

[Thomas Mueller]

I was unable to build mail/mpop with OpenSSL option selected but then switched to gnutls and succeeded.

This is a case where at most one of two or more options can be selected.

Is this a known problem, any relation to the Heartbleed problem that hit the news?

Most relevant part of log file is

This is a case where at most one of two or more options can be selected (GNUTLS or OPENSSL).
