Problems building firebird on 4.9-stable

[Norbert Koch]

Hi!

I'm unable to upgrade firebird to version 0.7.  The build breaks at

I've checked the dependencies and everything seems to be installed, so
I'm sort of clueless which header is missing or can't be found and why
that comes to pass.  The file /usr/X11R6/include/gtk-2.0/gtk/gtksocket.h
lies around.

Any pointers?

Thanks,
norbert.
