But as far as I can tell just about everything that runs on Linux is in
breach of this license model. Is not most of the stuff in Linux GPL? If so
then building any commercial software on Linux would breach this license
since just linking against various system libraries statically would put
you in breach of this. And what about dynamic linking?

Note FFTW is released under GPL so does this mean everything that links
against it that is not GPL is in breach of the GPL license?

Surely we just build any GPL software we want to use as a library and link
against it no? This appears to be what everyone else does.

All the best
