Can't run pgaccess

I seem to have tcl/tk configured properly.  By that, I mean I can run
wish or wishx and get a window (no tcl script running).  But when I run
pgacces.sh, it dies when it gets to the last line in main.tcl, which is
"main $argc $argv"

Any help is greatly appreciated

Here's the output:
****************************

    while executing
