On some distributions it can be found in the gtk2-devel package. The
file should be located in $LIBDIR/pkgconfig. Mine looks like:
$ cat /usr/lib/pkgconfig/gtk+-2.0.pc 
prefix=/usr
exec_prefix=/usr
libdir=/usr/lib
includedir=/usr/include
target=x11

gtk_binary_version=2.2.0
gtk_host=i386-redhat-linux-gnu

Name: GTK+
Description: GIMP Tool Kit (${target} target)
Version: 2.2.1
Requires: gdk-${target}-2.0 atk
Libs: -L${libdir} -lgtk-${target}-2.0 
Cflags: -I${includedir}/gtk-2.0 

It contains compiler flags and other needed things.

Great, I'm managing to compile j-g with free tools only, so I could
count on your help ;)

Mark, it seems that using the CLASSPATH variable does the job.

Thanks :)
