tcltrace is a single executable file with a tcl/tk gui.

. . tcltrace <scriptfile>

When the script to be traced has finished running (or you quit), an analysis window opens..

You can download the latest binary for linux here
The only requirements are that you have tcl/tk 8.5 and the 'vim editor' installed due to a 'custom vim widget' being used in the gui

You will need to make the downloaded file executable.
eg. chmod 755 tcltrace

.. and put it in your path .. either ./tcltrace or copy it to /usr/local/bin etc.
