Arrrgh! THIS makes tons of sense.
I don't know much about this, but why don't these installs establish and
reference symlinks. I.e., ruby gets installed and established a symlink
which anything can access to find it, and likewise with rubygems. That
would keep this sort of crap from happening. This mess is the result of
someone who should know better not thinking things through. For compiled
ruby to go one place and package manager ruby another??? This is a
thoughtful solution to anything at all? The guy behind this surely has a
career in investment banking waiting for him somewhere.
I compiled my ruby from source because I was having some problems with
the package manager version. But then rubygems wouldn't install. Kept
insisting that some libraries which WERE there were not. An expert I had
look at the mess couldn't make sense of it. I then installed rubygems
from the package manager. No problems. Except ruby cannot find the gems.
I will try try to use your idea to fix this mess when I have a little
more time this evening.
Thanks so much for your thoughts.
Tom
