Hey Marcela, sharing of code by language interpreters that are not fully
compatible with each other is a big change to how Fedora ships packages.
This needs to be considered by FPC to decide if it's okay to do so and if
the methods suggested protect user's who are just trying to install working
versions of the applications.

Personally, I'm leaning towards liking the concept.  Agreeing with the idea
of a script to multiplex between different interpreters for applications.
And thinking that the Provides and Requires proposal is insufficient.  But
like I say, I don't know what the rest of FPC thinks.  So I don't yet know
if we'll need to make small alterations to the Provides and Requires
proposal or throw it out and figure out a different way to do it (or if the
whole concept will be deemed unfit).

I'll know more after the meeting.
