#    1. Make this script executable:  "chmod +x macosx_abs.sh"  #
#    2. Build as root:  "sudo ./macosx-abs.sh"                  #
#    3. Tested on:  Mac OS X Panther 10.4.2,                    #
#       Absoft 9.2 Fortran compilers,                           #
#       GCC version 4.0 C/C++ compilers                         #
