It's okay. :)

Hmmm. Okay. It looks like my install of RT recreates the obj directory
- sorry for the assumptive advice.
Here is a better command for clearing your mason cache, but leaving
the obj directory:
% sudo find /var/cache/request-tracker4/mason_data/obj -mindepth 1 -delete
I've made www-data the owner, but as I'm invoking this

On my installs:
www-data:www-data and 0755
You should only need to set that for the "obj" directory as the RT
process will build the rest of hierarchy.
Oh, I should say, the FCGI command I use is:

It almost sounds like your RT_SiteConfig.pm has invalid perl syntax.
Run:
perl -c /etc/request-tracker4/RT_SiteConfig.pm
Both before and after enabling and disabling your extension and
running the update-rt-siteconfig.
-m
