Are you familiar with autoconf? It's just a question of passing
locations to configure via command line options. See:

perfectly reasonable...

I'm using the same for ns2.1b4 and a more recent snapshot.  For you,
you might need to specify different otcl/tclcl when configuring each
ns, but you'll probably still be using the same Tcl/Tk versions.

can do.

well, giving the full location of the ns binary in its own ns-2 tree,
although I have a couple of symlinks set up rather than overloading my
path with additions. Personal choice, really.

specify it with the configure --with-otcl etc. Read the compiler
output to make sure it picks up on the directory you specified.
