Subject: Re: RubyGems 1.0.0

I was on Fiesty which still had 1.8.4 I think, and I presumed my problem was due to the initial gem 
release didn't work with 1.8.4

So I upgraded to a source install of 1.8.6 to /usr/local/lib and thats when I ran into more (non gem 
related) problems.

I finally solved them all, but from now on I'm sticking with source installs and staying away from 
apt installs for any ruby related thing.

One gotcha is when you move from /usr/lib to /usr/local/lib you need to pretty much reboot to flush 
the library caches etc. Also for safe measure I renamed all the /usr/bin and /usr/lib/ruby stuff to 
.old so I don't pick them up. Especially note that apt seems to have a /usr/lib/siteruby whereas 
source installs have a /usr/local/lib/ruby/siteruby which does seem to confuse a lot of things.

Lastly I think mixing and matching apt installs with source installs seems very problematical, so 
avoid it :) Unfortunately the apt system never has the latest gem or ruby so if you need them go for 
source installs.

One thing I didn't try which may have worked better was to build a ruby apt package and install 
that, ditto for gem.

Best of luck!
