Please see bugfix 28 on
http://amber.scripps.edu/bugfixes90.html
This should fix your problem. Remember to do a make clean in $AMBERHOME/src/
after applying it.

First of all start with a fresh copy of the amber source code and apply
bugfix.all from the amber website. Then try building the code. Then cd
$AMBERHOME/test/; make and see what test failures you get. If these all work
fine or with only minor roundoff differences then the problem is likely with
your simulation protocol and more details will be required to find out what
is going on. If the tests cases fail please send us some more details
including the TEST_FAILURES.diff file from the test directory and your g95
version number, machine specs, src/config.h file etc.
All the best
Ross
