Are you sure you are planning to analyze fluctuation matrices in ptraj? (This
is a very specialized calculation.)
If not, you should probably just move on to something else...a newly rewritten
ptraj (all in C) will be released in a few weeks. So, people are not likely
to be highly motivated to try to track down your bug.
As to the "other tests" that failed, we would need to see details. I note
that your g95 is 20 months old: it *might* be worth downloading a newer version
from www.g95.org. But it might also be that your installation is (almost)
fully functional as is.

This has nothing to do with Amber code: errors in new2oldparm.f are invariably
problems with the compiler installation. Make sure that you can compile
simple fortran programs on your machine.
Others on the list may know the answer to how to install ifort on Xeons.
Did you Google on the error message listed above?
