svn info only operates on local copies so you'd have to check out the 
latest and then do an info to find out what you got and use that to 
pull later components. The logic is yukky.

Yes I started down this path but worried if I was going to break 
something in all that cleaning and makefile tweaking that happens. Now 
that I know more about the build I see that's not a problem so I 
updated the script to do all the checkouts in one shot.

This also avoids a problem where someone can do an initial build on 
just the frontend and then later decides to include the plugins. With 
update you'd have to look at what's there and what's needed and update 
some and co others and who knows what else.

Cool. But, as part of the script? Oh, I guess a mention somewhere in 
the -help text.

At first I thought you meant nohead to be more like "inplace" which 
might be a better term for this. I made a few changes in that direction 
but decided it would be too much trouble to decipher all that makefile 
cleaning and tweaking so I stopped. There are a few short-circuit "if 
nohead" lines that are pointless but don't hurt.

Everything else in there is good stuff that should make it into svn. 
This version makes the build more reliable and and more of a turnkey 
affair. If any of it doesn't look quite right I'll be happy to supply 
cheerleading.

One remaining issue is the behaviour of the retail OSX which script. It 
always gives output but the plugins configure script depends on it 
being silent when a file isn't found. If, like me, you've got 
DarwinPorts then you can get a nicer one in /sw/bin which is why I have 
that added to the path. Not sure what to do otherwise. Perhaps test for 
a broken which and die.
