Why does this tool installed on unix not work?

[northfield]

[w1111@node00 w1111]$ globus-personal-gatekeeper
/opt/globus2/bin/globus-personal-gatekeeper: /opt/globus2/bin/libexec/globus-scr
ipt-initializer: No such file or director

something very strange is happening.
But I don't know why?????

I have a tool at /opt/globus2/bin
[w1111@node00 bin]$ ls
...
globus-personal-gatekeeper
...
globus-job-run
[w1111@node00 bin]$ globus-personal-gatekeeper
/opt/globus2/bin/globus-personal-gatekeeper: /opt/globus2/bin/libexec/globus-scr
ipt-initializer: No such file or directory

Why is this happening???

The thing is I was able to make it work once before, but know I always get this error.

I have put this command in my .bashrc file:

# .bashrc

# User specific aliases and functions

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

# local addition
if [ -f /usr/local/etc/cluster ]; then
. /usr/local/etc/cluster
fi

export PATH=$PATH:/opt/globus2/bin
export GLOBUS_LOCATION=/opt/globus2/bin

Please help???
