Hi Jeremy:

   Do you have the 32 bit compatibility libraries installed?  For the 
binaries in question, what does

	ldd /usr/users/gcg/linuxbin/gcgbin/execute/mapplot

report?  There should be nothing with an "unknown" library entry there. 
  Also, what do

	file /usr/users/gcg/linuxbin/gcgbin/execute/mapplot


	file /usr/users/gcg/linuxbin/gcgbin/oblib/libgenshare.so
