Comment (by mojca@…):

 Based on the error:
 {{{
 I/O error : Attempt to load network entity
 http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
 warning: failed to load external entity
 "http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl"

         ...propagated at Po4aBuilder.pm line 268.
 }}}
 I would suspect that it might have something to do with:
 {{{
 > port provides /opt/local/lib/perl5/5.22/Pod/Man.pm
 /opt/local/lib/perl5/5.22/Pod/Man.pm is provided by: perl5.22
 > port provides /opt/local/lib/perl5/vendor_perl/5.22/Pod/Man.pm
 /opt/local/lib/perl5/vendor_perl/5.22/Pod/Man.pm is provided by:
 p5.22-podlators
 }}}
 where `p5.22-podlators` ships a newer version that `perl5.22`.

 But I have no clue. Adding `p5.22-podlators` to the list of dependencies
 and enabling trace mode doesn't solve the problem.
