1 - The parallel version of fftw library does not work on alpha (64 bit ) machine (fixed in  release 2.1r2)

2 - In the FIELD file if Ions are placed before water molecules a lot of warnings are printed in utaylor_mod.F90. This is harmless (fixed in release 2.1r2)
 

Version 2.1r2

1 - A stupid typo is present in the Makefile at the following lines

##### FastFourierTrasform (PUBFFT/FFTW/FFTW_MPI/SGIFFT/SP3FFT)
#           PUBFFT  : use the pubfft.f file in the dlprotein distribution
#           SGIFFT  : use the SGI fft routines
#           PCCFFT  : use the SP3 fft parallel routines
#           FTTW    : use the FFTW routines (serial version)
             ^^^^
#           FTTW_MPI: use the FFTW routines (parallel version)
             ^^^^
#           default: PUBFFT

The two underlined words must be read as: FFTW
This means that the right precompiler flag to use FFTW library is
FFTW ( not FTTW !!). It will be fixed next release
