scm command line

Hi,
I'm configuring scm login on the linux box.
1. The box has scmtools installed and users ssh to the box to do scm
2. scm is added to the path, the .bash_profile looks like
# .bash_profile

# Get the aliases and functions
if ; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/opt/IBM/TeamConcert/scmtools/eclipse:/opt/IBM/TeamConcert/
jdk/jre/bin

export PATH

Problem:
each time a user tries to run 'scm login -r https://localhost:9443/jazz/ -u USERNAME -P PASSWORD -n jazz', the following error occurs:

libjsig.so: cannot open shared object file: No such file or directory

HOWEVER, When the user at this time run vi /opt/IBM/TeamConcert/scmtools/eclipse/scm.ini, do nothing in the vi and exit, the above command runs perfectly well!

Anyone know why?
PS: if the user don't rely on the path and run the scm under /opt/IBM/TeamConcert/rcmtools/eclipse, the problem is gone.
