specifically, paragraph 4.c:
[you may distribnuted modifed Perl provided you] give non-standard executables non-standard names, and clearly document the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version.
So, something like "Whizzomatic can be automated by writing whizz-scripts, using Perl! (To obtain Perl, see http://perl.org) would allow commercial distribution under 4.c. Para 8 allows Perl to fit into the bigger picture much like a compiler -- compile an executable and distribute the executable, that's not a distribution of the compiler. Compose an aggregation of perl and a perl script and distribute the aggregation, that's not a distributioon of Perl.
