thanks for the info, Mr.David.. but when i try to compile gromacs, it
returns an error. the following is an excerpt from the output of 'make'.

/usr/local/lib/libfftw3f.a(the-planner.o) definition of _fftwf_the_planner
in section (__TEXT,__text)
/usr/local/lib/libfftw3f.a(version.o) definition of _fftwf_cc in section
(__TEXT,__cstring)
/usr/local/lib/libfftw3f.a(version.o) definition of _fftwf_codelet_optim in
section (__TEXT,__cstring)
/usr/local/lib/libfftw3f.a(version.o) definition of _fftwf_version in
section (__TEXT,__cstring)
/usr/bin/libtool: internal link edit command failed
make[4]: *** [libgmx.la] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1

i think Mr.Jack Howarth had already pointed the same thing out, sometime
back. any suggestion!?

regards,
kota.
