Been trying for a while to get komodo 6 working on PC-BSD 9 but today there was an update to PC-BSD-9Beta1-5 that allowed me to get komodoedit 6 working with only a few adjustments. Here's what I did:

Download the binary Linux x86 release of komodo edit 6 (also when on a amd64 machine)
Install using the install.sh file to your favorite dir.
Find a 32bit linux system to get the following libs: (or take the ones in the attachment, taken from Debian Squeeze)
- libdbus-1.so.3
- libdbus-glib-1.so.2
And copy those to /compat/linux/lib/

Put the komodo executable in your path or link it and you can start working with komodo 6.

Have fun!!

UPDATE:

I've also added a portdir as attachment if you'd rather use ports to install/uninstall. It will also pull-in the Linuxlibs for you to make it a hands-free install.
