FreeBSD 10.3 with LibreSSL installed: [helmut@BSDHelmut1064 ~]$ sudo portupgrade mail/fetchmail [Reading data from pkg(8) ... - 307 packages found - done] ** Port marked as IGNORE: mail/fetchmail: You are using OpenSSL from ports and have selected GSSAPI from base, please select another GSSAPI value ** Listing the failed packages (-:ignored / *:skipped / !:failed) - mail/fetchmail (marked as IGNORE) [helmut@BSDHelmut1064 ~]$ Do I really have to do a full installation of Heimdal or MIT from ports when using LibreSSL?
If you would like to use fetchmail's GSSAPI support with non-baseSSL, or for that matter GSSAPI support in any application, then you do indeed need either Heimdal or MIT to provide that support. This is not specific to fetchmail: https://svnweb.freebsd.org/ports?view=revision&revision=420788 As you're using LibreSSL, you probably want to be aware of this issue as well: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198527
