Compile problem with Xastir on Suse 9.1

I am having a problem getting Xastir to compile on Suse 9.1 as the ./configure script says it can not find the Motif devel files. Per Yast they are installed. Even went so far as to remove Motif and install Lesstif with the same results. As I am a fairly new user of Linux I have no idea where to look. Any help would be greatly appreciated. Gale KC4PL
