Hi @DrDinosaur,
You need to look for the Gemfile.plugins file under ./lib/vendor/:
/tmp/dradisframework-linux-x86/lib/vendor$ ls
total 32
drwxr-xr-x 3 etd wheel 102 17 Feb 12:44 .bundle/
-rw-r--r-- 1 etd wheel 3589 17 Feb 12:44 Gemfile
-rw-r--r-- 1 etd wheel 6325 17 Feb 12:44 Gemfile.lock
-rw-r--r-- 1 etd wheel 1866 17 Feb 12:44 Gemfile.plugins
drwxr-xr-x 4 etd wheel 136 17 Feb 12:44 engines/
drwxr-xr-x 3 etd wheel 102 16 Feb 17:58 ruby
After tweaking, you’ll need to run bundle install to get the new plugins.
HTH,
Daniel
