 Current version in MacPorts is 1.3.1, released 2002.

 According to https://www.emacswiki.org/emacs/PsgmlMode there are
 updated/forked versions available which address compatibility with Emacs
 24+.

 Or, given how long this port has may have been broken for (Emacs 24 was
 released in 2012), should it be removed? (I personally do not need this
 port.)
