I installed SWI Prolog, but it wanted to adopt the .pl extension for prolog files. Clearly this was something I couldn't live with, so I adopted the .pro extension instead. I also changed the default installation from "program files\pl" to "\program files\prolog". Installation failed the first time saying it couldn't write registry settings, however I ran it again, with the same settings and it run without error. Installing the dependency Language::Prolog::Sugar, was error free. But the Makefile for Language::Prolog::Yaswi is crashing with:

C:\Perl\Language-Prolog-Yaswi-0.18>perl Makefile.PL
Set up gcc environment - 3.4.5 (mingw special)
Checking if your kit is complete...
Looks good
retrieving SWI-Prolog configuration:
  running 'plcon.exe -dump-runtime-variables'
'plcon.exe' is not recognized as an internal or external command,
operable program or batch file.
unable to run swi-prolog command 'plcon.exe': 256
Aborting...

Manual Makefile installs are new for me, I've just used PPM before. Have I done anything obviously wrong?

Thanks
