make gconfig not working on Fedora 17

If you try to compile the Linux kernel from source using make gconfig it will probably not work on Fedora 17 spewing a message similar to: 

*

* Unable to find the GTK+ installation. Please make sure that

* the GTK+ 2.0 development package is correctly installed...

* You need gtk+-2.0, glib-2.0 and libglade-2.0.

*                 

Although libglade2 is present by default on Fedora 17, this error comes up because gtk internally needs the headers for libglade-2.0

So, you need libglade-devel. Yum it. As root: 

# yum install libglade-devel
