Hello,
The maintainer of the MacOS X version of Modeller 6.0 may
want to consider installing fink 0.6.2 (from fink.sourceforge.net)
and 'fink install' the gcc 3.4 g77 compiler to do the next build of
Modeller 6.0 under Panther. While the gcc 3.4 g77 compiler isn't
as agressive in optimization as the IBM XL Fortran for MacOS X
compiler, it does a much better job than before (if used at -O3).
This now enables the DFA ppc support in the compiler.
I just mention this because the Absoft build of modeller seems
a bit sluggish. Unless you have the very latest Absoft MacOSX
compilers they might not even generate code as fast as the
g77 from gcc 3.4. Otherwise perhaps you need a much higher
optimization level setting with the Absoft compiler than you
are currently using.

ps If you use g77 3.4 and find that you get compilation error
at -O3 you might selectively add -fno-globals to those specific
files. The use of -fno-globals on all the source files will
impact the performance of the generated code because it disables
higher order optimizations. So that should be avoided.
