Dear Pohl,
I think your prefix directory /usr/local/gromacs332 is not accesible for writting. Try to creat new directories with other names and use those in prefix.

First, they need to fix their typo in their configure command line, as mentioned by another poster. Otherwise, it isn't known that the failure to write these files is caused by permission issues, rather than their malformed filename.

Have you setenv for the include and lib of the fftw files?

(For instance, assume we have installed FFTW with --prefix=/home/joe/fftw. If your shell is tcsh, you set
setenv CPPFLAGS -I/home/joe/fftw/include
setenv LDFLAGS -L/home/joe/fftw/lib or, if you are using a bash shell:
export CPPFLAGS=-I/home/joe/fftw/include
export LDFLAGS=-L/home/joe/fftw/lib )

If not do that.

This works, but it's superior to leave the environment alone and instead to use "./configure CPPFLAGS=-I/home/joe/fftw/include LDFLAGS=-L/home/joe/fftw/lib". Not only do you avoid having to get it right for each shell, but you don't pollute your environment for this shell (small point), and (more importantly) in config.log you will have a record of the command line for any subsequent time you need to run configure. When someone has to come back in 6 months to configure an MPI or double-precision version, the record of what was done last time saves on repeated detective work.

If you need multiple -I or -L flags, then enclosing them in quotes, separated by spaces, works, i.e. "./configure LDFLAGS='-L/some/lib -L/some/other/lib'"
