Exactly, and without looking too closely ruby seems to be changing
even faster.  There is not going to be a perfect solution to this
problem, especially if you consider separately packaged libraries that
really have to change over time, but RPM needs to handle concurrent
multi-versioned targets gracefully or they should just change the name
when it is not the same language anymore and won't execute its own old
syntax so the packages don't conflict.
