Renaming net/ceph to net/ceph12

[Willem Jan Withagen]

Hi,

I there a ports committer that can do that for me if it is just a mater 
of `fix Makefile && svn rename` greatly appreciated.

If it needs more work, can somebody explain to me what more is needed?

After this is done, I'll submit a new ceph 12.2.11 version once it is out.
And I'll upload the first version of ceph 13.2.x

Thanx,
