That's certainly ok when there are only a few, but I have almost
200 on my system. I like to run 'gem update' on a daily basis to
keep current. Unfortunately, there are a lot of gems out there
whose latest versions are no longer compatible with rails 2.
I realize that this is more of a convenience matter, but I am
surprised that it doesn't exist. Maintaining a global list of
either gem versions to skip or gem versions to install, much like
an individual gemspec does, seems like it would be beneficial.
Particularly when an updated older version is made available, like
when rails 2.3.11 was released.
Actually, I was looking for global gem management not associated
with any particular application. It looks like bundler may do the
trick with a Gemfile in my home dir. Initially, it was installing
some odd version choices with regard to my version restrictions,
but I'll figure it out.
