Hey again,

Are you really doing an in-source build? Build and source directory are equal 
in this case. This is required at the moment to be able to enable the private-
header feature in GammaRay.

You don't need to, even shouldn't set this variable manually.

I just successfully build GammaRay with the private-header feature enabled.
All I had to do was the following:
* Build Qt4 in-source with './configure -developer-build' (let's say in ~/foo)
* Add ~/foo/bin to PATH
* Then just configure (no extra parameters needed) and build GammaRay

That's about it,
