Marcus -
The original CD that we received had - or was supposed to have - a suitable version of gcc and a development environment (filesystem). However, there was a problem of some sort with the pressing and the files were not readable. The CD that we distribute has a different point version (1.2b instead of 1.2) and does
not include the necessary files. The best I could find was version 1.1
here. Presumably other methods and sources are available, and the wiki page & instructions you found are probably the best guide.
