Subject: AMBER: Amber10 Installation error - incorrect file suffix

Dear, Amber developers
I'm trying to install amber10 on the cluster
xlf90 ver. 9.1 compiler is being used for compiling source code and
OS of the cluster is 'SuSe Linux Enterprise Server 9 for ppc64/kernel

While compiling serial version of amber, incorrect file suffix error
I guess that the compile is not recognizing F90 as suffix of fortran90 code.

make[2]: Entering directory `/home/drfaust/apps/amber10/src/dcqtp'
cd mod; make QMMM=-DQMMM -f Makefile.dcsander libdivcon.a
make[3]: Entering directory `/home/drfaust/apps/amber10/src/dcqtp/mod'
xlf90 -c -qfixed -qfree=f90 -I../../sander -I../src/include -DHAS_LAPACK
-DQMMM -o ../obj/kinds.o ../src/main/kinds.F90
xlf90: 1501-218 file ../src/main/kinds.F90 contains an incorrect file suffix
make[3]: *** [../obj/kinds.o] Error 1

How can I fix this problem efficiently?
I'm planning to change all suffixes, F90 to f and compile the code again.
However, I'm not sure whether it will work or not :)

If you have any suggestion on the problem, please let me know.
