[PCc0d3r <pcc0d3r basari net tr>]

Hi,
I downloaded the 1.2.8 version of the gtk and glib. Firstly i compiled
glib succesfully. Then i tried to compile gtk too. When i typed configure
command it is always giving me cannot find glib-conf and glib. But i
installed glib to /usr/local/lib/glib/
--------------------
like that:
checking glib-conf  no
checking glib >= 1.2.8   no

Then i tried that command :
$ ./configure --prefix=/usr/local/lib/glib
but it didn't worked.

Please, but please help me immediatly!
