You need to be more precise, as there are a number of types of add-ons,
all of which are somewhat different.

Theres really four generic types of contributions.
Firstly, the ScripActions, ScripConditions and extra pages within the
WebRT directory. These wouldn't require any assistance from such a tool,
as they all (should be) within the RT library scope and called using the
RT API methods by RT itself. ( ie, 'use lib' shouldn't occur within a
RT::Action, RT::Condition or any file under WebRT/html ).
Secondly, standalone scripts that use the RT libraries. These do need
substitutions of RT library paths, but thats it. The rest of the RT
infrastructure takes care of the mundane tasks such as talking to the
Thirdly, scripts which manipulate the database directly. You probably
don't want to attempt to change those script's ideas about where libraries

And Fourthly, localised changes to the RT libraries or existing webpages.
For the latter, RT currently defines a separate directory (see
$MasonLocalComponentRoot), where localised overrides to the page can be
placed, with (I assume) your own version control. for the former, the
next version of RT has a similar 'Overlay' concept, which allows localised
changes to libraries to be in separate files, again with your own version
However, to address the 'package management' issue, you could always use

does keep checksums and etc.

I'm on-call at the moment. What is this strange 'holiday' word people
keep referencing? ;)
