1) Download a TclKit binary for your platform on the URL Mats gave.
2) Make sure the binary is executable on your platform
3) Download the Coccinella sources and unpack them
4) Run the tclkit binary to start Coccinella, either (assuming you are in the coccinella directory):
a) ./tclkit ./Coccinella.tcl
b) ./tclkit
source Coccinella.tcl
Note: on Mac OS X you also can open the Coccinella.app directory and simply replace the tclkit with another version; that should work too.
