For other flavors of Linux:  The version of glibc that the Linux OS uses must be identified.  If the attempt to install MOPAC works, great!  If it complains that glibc is missing, identify which version of glibc is used by the Linux operating system, then use the appropriate CentOS version.  These are: CentOS 5: glibc-2.5 CentOS 6: glibc-2.12, CentOS 7: glibc-2.17.
