Missing lib files for acrosslite install
 

I am trying to install a crossword program that, according to the ReadMe, needs a number of specific libs in the loader search path. I have a number of them in /usr/X11R6/lib but I am missing others. I hace tried to *locate* them and they do not exist in my system. Anyone know where I can find these? I am missing the following: libc.so.5, libbg++.so.27, libstdc++.so.27, libm.so.5, and libXm.so.2.0. Thanks.
