Hey just to follow up, the mistake was on my part I believe. I was using
the ancient ruby-activerecord package, which will soon be retired as it
has long since been replaced w/ rubygem-activerecord.
I'm still not sure why ruby-activerecord didn't work, especially with
rubygem-activesupport installed, but trying this again w/
rubygem-activerecord results in a successful build / install.
Thanks for the help,
