problem of running Source Navigator
 

I met the problem for several days and hope anyone can help me.
I have installed Source Navigator 5.2b2 on my Debian Sarge, however, I got problems when executing it:
# snavigator (enter)
Can't find a usable init.tcl in the following directories:
/share/tcl8.3

I have installed tcl packages and tk packages,and it's so weird.
