gcc -o base base.c 'pkg-config --cflags --libs gtk+-2.0'执行不过去啊？

Question

我刚装好了RedHat Linux 9,请问下我的GTK版本怎么看啊？
[root@localhost test_gtk]# rpm -qa|grep gtk
pygtk2-libglade-1.99.14-4
gtk-engines-0.11-16
mtr-gtk-0.52-2
gtk+-1.2.10-25
gtk2-2.2.1-4
gnome-python2-gtkhtml2-1.99.14-5
usermode-gtk-1.67-2
authconfig-gtk-4.3.4-1
gtkam-0.1.7-3
gtkhtml-1.1.8-5
gtk2-engines-2.2.0-2
gtkhtml2-2.2.0-5
pygtk2-1.99.14-4
[root@localhost test_gtk]# pkg-config --modversion gtk+-2.0
Package gtk+-2.0 was not found in the pkg-config search path.

我该怎么弄呢？请大侠告知
