Please describe the problem:
Trying to build the module (using jhbuild) fails if there is no gdk even though all checks of configure passed. It seems to be included in at least one of the examples ("seek") but also with --disable-examples it fails because of the inlcude of gdk in "test-colorkey".

Steps to reproduce:
1. 
2. 
3. 


Actual results:


Expected results:


Does this happen every time?
