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.
