I accepted the challenge and tried to download SWI Prolog from Git and compile it myself.
Thanks to the marvelous Codeblocks PND I succeede!
It's only the pure Prolog interpreter, no libraries and such.
And it only runs from the Codeblocks developement console because of a missing dependency otherwise - but it's enough to get in touch with the language and doing some experiments.
A full featured PND that could be used for some real world stuff would still be appreciated... ^_^
