seems you your not root on this machine.
Ask your local sysadmin to install it, if you want to have this 
in /usr/

else do ./configure --help
Than you set --prefix=/your/home/dir/fftw  << all installation will go into 
this

See upside, you haven^t installed fftw correctly.
With gromacs you do the same ./configure with --prefix
