========================
The server error output;
========================
xxx@hostname:/export/apps/wapp$ ./wapptclsh /home/dev/payment/webNATS.tcl --server 8080
Listening for HTTP requests on TCP port 8080
ERROR: can't find package nats
    while executing
"package require nats"
    (procedure "wapp-page-testpackage" line 2)
    invoked from within
"wapp-page-$mname"

=====================
However, from tclsh;
=====================
xxx@hostname:/export/apps/wapp$ tclsh
% 
% package require nats
0.9
% 

There are too many dependencies so I can't source the nats package directly into my script as a work-around. 

I cannot access any of my installed packages, any insights will be appreciated
