[webkit-dev] DerivedSources.make: Another try?

[Filip Pizlo]

This discussion about DerivedSources is too abstract for me. 

If the only thing that DerivedSources.make looks for is python, perl, and ruby, then there has got to be a way for cmake to pass arguments to DerivedSources to tell it where to find those binaries.
