Feel free to write one :)

Yeah. I think chicken-install could have a simple alist of
license->incompatible licenses  or license->compatible licenses
for each license.

I'm not sure what to do about unknowns though.  I'm sure nobody is going
to like checking each and every license's interaction with other licenses.

Agreed.  But some projects by people hacking around at home have a
tendency to become larger, and then it can become an issue.  So I
think the warning should be VERY INSISTENT about it ;)

We could do it ala pkgsrc: block it by default, and allow it if you
set an override (which should be mentioned in the warning message).

But let's start with a simple warning.

"The process of preparing programs for a digital computer
 is especially attractive, not only because it can be economically
 and scientifically rewarding, but also because it can be an aesthetic
 experience much like composing poetry or music."
