The world outside V3.

I'm not sure.

In any case, what you're saying is that we can't do this because our 
build system is lame, not for any reason of principle.  I can believe that.

The fix would be to install the compiler before building V3, or at least 
do some kind of dummy installation.  We've been wanting to do that for a 
while; that would avoid all the hokey -B/-L gunk we have to do when 
building libraries.  But, I can believe that it doesn't work with our 
current build system.

Thanks,
