Error install lessTif

Hi all,
I would like to install lesstif-0.95.2 on a RHEL Client release 5.1 system. ./configure gives me this error message:

"The development package for the X Window System is required to compile LessTif, must be at least X11r5."

I downloaded and installed these rpms:

x11r6-contrib-6.8.2-77311cl.i386.rpm
libxaw8-6.8.2-77311cl.i386.rpm
xorg-x11-libs-common-6.8.2-77311cl.i386.rpm

./configure still gives me the same error message.
Any help? Thanks.
Austin-
