It would be great if you could create the patch and pick up
maintainership. Making a patch is easy, Just download manaully the
tarball the port uses, make a backup copy of the file to be changed, make
the changes, and diff the old against the new.
cp file file.org
diff -u file.org file >patch-file
Now you've got a patch. Now add the line:
to the portfile, and make your address the maintainer if you wish, and
then do the same to the portfile.
diff -u Portfile.org Portfile >Portfile.diff
Now make a trac ticket and submit both patch files and that's it. If no
one notices it you could ping the list.
