Getting around DJB's licence...

So you can't redistribute a modified version - so what.  This should only
be a hindrence to distributing binary ONLY ports distributions.  I haven't
read anything, anywhere, yet, that says you can't ship it as src tarball
and patches.  The only difference is when you install the port you have
to do some work: unextract tarball, apply patches and compile.  Worst
comes to worst, the install for qmail would have a rather length setup
shell script action.
