Dear Jason and David:
Thank you very much for your prompt response. I was able to install macports. However while I was configuring, I got the error message below. The suggested log file is too long for Amber mailing list. Hope I am not taking too much of your time.
Thanks again,
MM

How did you install it? Because the error you are getting is likely
caused by how you installed gfortran. Since Amber relies on cross-linking
Fortran and C codes, libgfortran is needed at link time to compile many
programs. If it's not available, Amber won't work.
The typical way that we recommend users get gfortran is through MacPorts.
You can see my Mac tutorial here: http://jswails.wikidot.com/mac-os-x
It's a bit dated, but getting MacPorts installed and getting gcc installed
should still be up-to-date.
HTH,
Jason
