I see.

OK, maybe a concrete example would help.
Currently on my system I get the following for reek, when trying to

Kevin Rutherford has been unable to reproduce this, even noting the
gems that show up in those diagnostics. Now, I'm not using Bundler,
so it will have no record of my setup. How do I export my
collection of gems in such a way that a setup with the same gems can
be installed on some machine? Then some things might be eliminated
from the enquiry.
I think what I propose would do this. I'm not entirely sure if I have
covered the case where the gems are in one's .gem directory, or not, but
since I proposing to use the existing search mechanisms for this, I think
that would be covered.
On the other hand, I don't see how Bundler would help with this. [Which
is fair enough, it is outside the scope of its design (for recording
gems on a per project basis)].

Yes, this would be a good thing, but different from my existing problem.
