The widget code can be build with or without Motif support (the 'M' in
the symbols) with a preprocessor flag. I guess the rpm was
built/compiled without that flag. The flag is off by default since
Motif header files aren't always present.

Tnx Brian. Yeah, it seems to be the only one reason. I didn't try to do this
for now.
I'm also interested what is special with libGLw at:
http://downloads.sourceforge.net/mesa3d/libGLw.tar.gz?modtime=1011916800&big_mirror=0
that mesa guys put it as a separate lib for download?
