I appreciate the sentiment of those statements, but I don't think that
this practical. For example, some dependencies were available on
Fedora 13, but had to be manually built on Ubuntu 12.04. What then?

And some things get added to a distribution because they are used. If
we don't use them, then they never will get included. A catch-22.

gpr files were meant to be as close to a config file as possible, with
little chance of failing.

But I like the idea of a bit of code in the addon/plugin that would
try to run, and if it failed, then the addon/plugin would give a
message, and de-activate (hide) itself. Maybe that bit of code is just
the loading of it.
