Dear users,
I am a novice to both Linux and Gromacs. I am trying to install Gromacs on
my Linux PC and for that, I have installed FFTW-2.1.5. However, when I
give the last command "make install", I get the following error message:

[guest at localhost fftw-2.1.5]$ make install
Making install in fftw
make[1]: Entering directory
make[2]: Entering directory
/bin/sh ../mkinstalldirs /usr/local/lib
 /bin/sh ../libtool --mode=install /usr/bin/install -c  libfftw.la

/usr/bin/install: cannot create regular file `/usr/local/lib/libfftw.la':

make[2]: Leaving directory `/home/guest/Jaimin/gromacs-3.0.1/fftw-2.1.5/fftw'
make[1]: *** [install-am] Error 2
make[1]: Leaving directory `/home/guest/Jaimin/gromacs-3.0.1/fftw-2.1.5/fftw'
make: *** [install-recursive] Error 1

Now, when I give the follwoing command:
[guest at localhost gromacs-3.0.1]$ ./configure --enable-float

I get the following message:

checking for fftw.h... no
checking for sfftw.h... no
configure: error: Cannot find any single precision fftw.h or sfftw.h
Do you have single precision FFTW installed? If you are using packages,
note that you also need fftw-devel to compile GROMACS. You can find the
software at www.fftw.org, and detailed instructions at www.gromacs.org.

Can someone please guide me out?
Thanking you,
