I can't find where the existing PortGroups are actually defined (not in the man page, anyway, or a grep of the tree).  Could someone point me at (for example) the python and kde base definitions so I can see if that would be useful in this case?

The portgroup doesn't need to be versioned IMO. When a new version of ocaml is out, just update the version in the portgroup.


You can read the source of the portgroups here:

Consider how the php5extension portgroup prevents the problem you're worried about; see the pre-configure block on (currently) line 191:
