[Pw_forum] parallel environment not found

[Mahmoud Payami]

Dear PWSCF Users,

Before I try to use "./configure", I have installed MPI and run "mpdboot -n <number_of_hosts>" command successfully. So the environment for parallel is ok.
Afterwards, I try to use the "configure" command. As is seen at the end it does not detect parallel environment (although it detects all relevant mpicc, mpif77, ...):

-----------------------------------------------------------------
PWscf can take advantage of several optimized numerical libraries
(essl, fftw, mkl...). This configure script attempts to find them,
but may fail if they have been installed in non-standard locations.
 
The following libraries have been found:
  LIBS= -lfftw -L/usr/local/intel/mkl701/lib/32 -lmkl_lapack -lmkl_ia32 -lguide -lpthread
 
If any libraries are missing, you may specify a list of directories
to search and retry, as follows:
  ./configure LIBDIRS="list of directories, separated by spaces"
 
For more information, read the README.INSTALL file or the PWscf manuals.

Should I do anything more before running "./configure" to make it detect the parallel environment?
Any comment is highly appreciated.
