Not as far as I can tell.  But here's a revised patch that is both more
targeted and only using autoconf variables:

In 1997 a group of programmers started writing a desktop environment to fix a
travesty they didn't create.  Their program promptly found its way onto un*x
systems everywhere. Today, still opposed by a software monopolist, they survive
as soldiers of fortune.  If you share their vision, if you know you can help,
and if you can connect to internet, maybe you can join... the K-Team.
