Comment (by egall@…):

 These are the relevant lines in the configure.ac file:
 {{{
 AC_MSG_CHECKING([if Perl version >= 5.6.0])
 if "$PERL" -e "require v5.6.0"; then
         AC_MSG_RESULT([yes])
 else
         AC_MSG_RESULT([no])
         AC_MSG_ERROR([perl >= 5.6.0 is required for gtk-doc])
 fi
 }}}
 Simplifying it into a one-liner that can be executed manually on the
 command-line, it becomes: [[BR]] `if /opt/local/bin/perl -e "require
 v5.6.0"; then echo "yes"; else echo "no"; fi`, which returns "yes" for me:
 {{{
 $ if /opt/local/bin/perl -e "require v5.6.0"; then echo "yes"; else echo
 "no"; fi
 yes
 }}}
 what does `/opt/local/bin/perl --version` return for you? For me, it is:
 {{{
 $ /opt/local/bin/perl --version

 This is perl 5, version 12, subversion 5 (v5.12.5) built for darwin-
 thread-multi-2level

 Perhaps the gtk-doc Portfile could set `configure.perl` to a specific
 version that is known to work instead of just trusting that whatever
 `${prefix}/bin/perl` is a symlink to will work?
