CCL: installing CHARMM problems

 Sent to CCL by: Rick Venable [rvenable(a)]
 You should subscribe to the CHARMM forums at, and post
 this question in the "Installation and Performance" forum; be sure to
 provide more detail, such as the OS name and release version, likewise
 for the compilers you are using.
 Note that c32b2 was released in Feb 2006, and there are some important
 changes for 64-bit Linux since c31b1.
