I don't understand... move what line from where to where?

Not as far as I know. Simply changing a port, in any way, should cause the port to be reindexed.

In any given p5 port, the line should be:

perl5.branches 5.8 5.10 5.12 5.14 5.16

Or whatever subset of those branches that specific p5 port actually supports.

The way the perl5 portgroup is currently written, the perl5.branches line must appear before the perl5.setup line. I think it would be nice if it could appear after that line, but that would require changes to the perl5 portgroup, possibly large changes, such as the large changes I had to make to turn the php 1.0 portgroup into the php 1.1 portgroup.
