Problem with PATH variable and access

[Ivan Paganini]

Hello all. I am not sure this is the correct place to post this, but here it goes.
I am trying to install some scientific programs, like MPICH, ScaLAPACK, etc on a PIIIx2. The installations went well, until I had to call a command or library from the terminal. I have tried to set the PATH, MPI and MPI_LIB variables for root and normal users (authenticated by nis), with no sucess. I have put the correct lines on /etc/profile, /etc/bash.bashrc, and on ~/.bashrc for normal users, and /root/.bashrc, /root/.bash_profile and /root/.profile, with no sucess. The command is not found, even if the variable is correctly setted. Here is an output:
*******************************************
/root/.profile:
MPI=/opt/gnu/mpich-1.2.7/bin
export MPI
MPI_LIB=/opt/gnu/mpich-1.2.7/lib
export MPI_LIB
PATH=$PATH:/opt/gnu/mpich-1.2.7

/root/.bash_profile:
MPI=/opt/gnu/mpich-1.2.7/bin/
export MPI
MPI_LIB=/opt/gnu/mpich-1.2.7/lib/
export MPI_LIB

/user/.bashrc:
# .bashrc

# User specific aliases and functions

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

MPI=/opt/gnu/mpich-1.2.7/bin
export MPI
MPI_LIB=/opt/gnu/mpich-1.2.7/lib
export MPI_LIB
PATH=$PATH:/opt/gnu/mpich-1.2.7

/etc/profile:
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"
fi

if [ "$PS1" ]; then
  if [ "$BASH" ]; then
    PS1='[EMAIL PROTECTED]:\w\$ '
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi

export PATH

umask 022

************************************************************
I already have logged and dislogged, and even rebooted the system.
When I issue a env, the paths are there.

************************************************************
env:
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/opt/gnu/mpich-1.2.7:/opt/gnu/mpich-1.2.7/
PWD=/root
LANG=en_US
MPI=/opt/gnu/mpich-1.2.7/bin/
***************************************************************
What can be happening?
Thank you!
