FYI,
I have the swi-prolog-packages pkg working now. Problem was mostly a file
not compiled properly with __unix__ which led to a symbol not defined in
the .so file which led to the whole class library not properly loaded and
no proper error printed.

The error printing is improved now thanks to support from the SWI-Prolog
devloper, and the pkg both builds and installs now (it fires up Xvfb on
the way, as a working X connection is wanted too).

The current pkgs can be found at (updated!):
	www.feyrer.de/Misc/swi-prolog-lite.tgz
	www.feyrer.de/Misc/swi-prolog-package.tgz

What's left to do is
 * integrate with what Michael has added to pkgsrc-wip, esp. the bl3 code
 * probably do some cleanup
 * commit

I'll approach these points tomorrow after some sleep.
