Comment (by quentin@…):

 The only thing I noticed is that it still has the post-patch section to
 patch the script to use MacPorts' perl, but now there's no dependency tree
 that pulls in Perl. I'm not sure what the MacPorts standard is - either we
 can add a dependency on Perl, or remove the post-patch section and use the
 system perl. Do you know what packages usually do for that?
