my mistake: I changed `pkg-config ..` to $(..).
but neither $(shell pkg-config nor `pkg-config helped. same error.
question remains open.

any suggestions on my aother questions?

Currently I have glib2 installed, but there is also glib2-devel, and they conflict with each other.
Same for pango and pango-devel.
- What is the difference?
- Which should I use?

I don't know what the include path will be. 
- How should I use 'port provides glib.h' ?
