gtk 1.0.2 Compile problems

["Christopher S. Aker" <caker cybercomm net>]

This is probably a question that gets asked too many times on this list,
but I am at a loss trying to get GIMP and GTK to compile on my system.

I am running RedHat 4.2, kernel 2.0.33 on a 100Mhz 486.

running make, i get:

...

make[1]: Leaving directory `/home/caker/GIMP Stuff/gtk+-1.0.2'
make: *** [all-recursive-am] Error 2
[root@legend gtk+-1.0.2]#

Obviously, I am missing some kind of X header files.  Any comments?

Thanks,
