Subject: Re: setting up ruby on os x 10.2

Actually, if I remember correctly, /usr/local/bin *is* in the default
path; however, it's listed after /usr/bin, so the Apple-provided
version gets loaded first.

I've found it most useful to simply rename the pre-installed ruby
binaries (ruby, irb, erb, etc.) in /usr/bin with a '16' suffix, such as
'ruby16' -- that way, scripts with a hard-coded path to the Ruby
interpreter will fail at startup, rather than mysteriously running in
the older version (and usually not finding libraries, or hitting old
1.6.7 incompatibilities, or whatever).
