First, FWIW the ports that were originally committed to subversion-devel
and subversion-freebsd were my work. rodrigc did great work on the
www/serf port which subversion 1.5.0 can use if it's enabled.
These changes actually accomplish what peter asked for, a subversion-devel
that is a generic port of the 1.5.0 release candidate, and a -freebsd
version that is a slave to that port, to add some custom hacks that are
necessary only for accessing the FreeBSD Project repository.
So in the process, update COMMENTs, pkg-descrs, etc. to suit, and remove
the majority of the stuff from the -freebsd version since those things
are not needed for the slave port. Also make conditional those things
in the -devel port that need to be conditional in the master, and update
the definitions and defaultedness of the neon and serf OPTIONS.
It is intended that when devel/subversion is updated to 1.5.x that the
-freebsd port be pointed in that direction. Also, lev has volunteered to
maintain this stuff in the long term, I'm simply helping out right now
so that we can get it off the ground.
