 The Gaussian release document does not recommend that you compile your
 own and distributes the libraries on the release CD-ROM.  They have 
 funny names (not the ones listed in the release doc or in you mail), but 
 you can tell by the size and PIII prefix which is which. Use the distributed
 libraries on the CD-ROM.

 You also could be having a problem with your LD_LIBRARY_PATH variable.
 Comments from Doug Fox below outline the issues and remedy:
