Check the location of the system shared libraries.
The shared libraries libXt.a and libX11.a are normally stored in /usr/lpp/X11/lib/R5. The libXm.a library is normally located in either /usr/lpp/X11/Motif1.2/lib or /usr/lpp/X11/R5/Motif1.2.
If these shared libraries are located in directories different from the above, set the LIBPATH environment variable to indicate these other directories.
