From personal experience, I know that "_kio" is a symbol from LAM/
MPI -- not Open MPI. So be sure to be explicit about which MPI
implementation you want to use.
Also, I notice in Parallel::MPI::Simple that it simply tries to "-
lmpi" to get all the relevant MPI infrastructure. This will not work
with either LAM/MPI or Open MPI. I suggest using the "mpicc" wrapper
compiler instead of cc/gcc. For example:
perl Makefile.PL CC=mpicc
make
That seemed to work for me.

I am trying to install Perl Parallel::MPI::Simple (or Parallel::MPI)

I am getting the following error when i execute "make test":
Can't load 'blib/arch/auto/Parallel/MPI/Simple/Simple.so' for module
Parallel::MPI::Simple: blib/arch/auto/Parallel/MPI/Simple/Simple.so:
undefined symbol: _kio at

Compilation failed in require at ic.pl line 3.
BEGIN failed--compilation aborted at ic.pl line 3.
I tried installing the module in home directory and gave that path
"use
lib /home/path/Parallel::MPI::Simple" as the first line of the perl
program. I encountered the following error for "mpirun n1 perl
test.pl" :
"Undefined subroutine &main::MPI_Init called at test.pl line 4."
Any help to solve this issue would be greatly appreciated.
Thanks in advance.
