I'm not against making things work, but I'm strongly against using
package options for the wrong purpose.

It's not documented just as the dependencies on make or sh are not
documented -- Python is installed ~everywhere by default, so the
developers can't "imagine" that using Python can be a problem.

No. What is broken is Python, not gtk. So what should be fixed is
Python. But see below!

Again, making this an *option* is a very bad solution. I should have
elaborated more this morning on what could be better, but I didn't
have time. A more appropriate alternative is what Joerg suggested:
making it a separate package. This way you can keep correct track of
dependencies in all platforms, at the same time, and not break
The eventual best solution for this would be to add support to pkgsrc
to generate different binary packages form the same source and do what
Linux distributions do: a libgtk package and a libgtk-dev package, out
of the same build, and each with different dependency sets. But,
unfortunately, we are far from this :-( Thus, creating a manual,
separate package is the closest alternative.
