netsurf and gtk+ build error

Hi guys!

I try to build netsurf in the distribution PCLinuxOS, but get the
following error:

------------------cut-------------------
PKG.CNFG: Curl (libcurl) enabled
PKG.CNFG: GTK-2 (gtk+-2.0) failed
gtk/Makefile.target:62: *** Unable to find library for: GTK-2 (gtk+-2.0). Stop.
------------------cut-------------------

I extremely wondering! Because GTK library is installed, this is
evidenced by the following commands:

$ pkg-config --modversion gtk+-2.0
2.24.22

$ ls /usr/lib64/pkgconfig/gtk+-2.0.pc
/usr/lib64/pkgconfig/gtk+-2.0.pc

Sources of netsurf took here:
http://download.netsurf-browser.org/netsurf/releases/source-full/netsurf-all-3.3.tar.gz


What to do? Please help.
