Hi, all,
I have some problems with installation of QE. First of all :/configure is not 
able to recognize parallel environment unless I define

./configure F77=gfortran F90=gfortran MPIF90=mpif90

but when I run 

make all 

it returns 

startup.f90:(.text+0x554): undefined reference to `iargc_'
startup.f90:(.text+0x6b2): undefined reference to `iargc_'
collect2: ld returned 1 exit status
make[1]: *** [pw.x] Error 1
make[1]: Leaving directory `/quantumespresso/espresso-3.2.2/PW'
make: *** [pw] Error 2
[root at xeon espresso-3.2.2]# 

This is problem with versions 3.1.1, 3.2.2 and 3.2.3. But when I define

./configure F77=gfortran F90=gfortran

compilation is possible for 3.1.1 in serial version.
(My operative system is Centos 5.1, I have 2 Intel Xeon processors).
If anybody faced similar problems and managed to solve them I would really 
appreciate help.
