Komodo-IDE

Komodo-IDE is an excellent debugger for TCL.. and for many other languages. It requires a license to use, but a free license is available for non-commercial use.

Installing Komodo-IDE requires you first install the Komodo-Edit package.

sudo pkg install komodo-edit

this installs the required linux-compat system. and possibly more but this is what works.

From the package installer:

>>This package needs linsysfs mounted on /compat/linux/sys. Add the following line to /etc/fstab:
linsysfs /compat/linux/sys linsysfs rw 0 0
Then run mount /compat/linux/sys
