Building Gtk+ (pkg-config not found)

[Janos Blazi <jblazi gmx de>]

I downloaded pkg-config... and installed it with

./configure --prefix/opt/gtk
make
make install

After this I tried to build glib 2.02 but received the configuration error
"pkg-config not found".
I can see pkg-config in the directory /opt/gtk/bin and I also set tha
variable PKG_CONFIG_PATH (by setting the variable I mean I entered this line into
bash and then I entered export PKG_CONFIG_PATH though as I am a newbie I do
not know exactly what this mean).

Can anybody help me?

TIA, J.B.
