Hmm...That's a strange one. It makes me think the Ruby gems server is broken. I'll look into it...it could also be that we're doing something stupid or maybe missing some sort of updatee step. But I thought tthe gems db updated everytime you used it non-locally.
What happens if you run the following on the command line:
gem sources -l

Hi Joe,
This is what I get running gem sources -l

After waiting a couple of hours I tried the install script one more time. It went further this time stopping at this error:
Now installing Ruby on Rails version 1.2.3 ..

You've got all sorts of trouble there. ;-)
Obviously, you're short of memory.
Is this a VPS of some sort? (Virtuozzo/OpenVZ has a notorious and nasty memory bug that has been present for well over a year...if the system is over-subscribed, at all, it'll lead to mysterious memory allocation errors.)

Yes, it is running as an Ubuntu 6.06 VPS using OpenVZ, I have a dedicated ram of 256 with burstable ram of 512.
I went ahead and installed rails via apt-get, which worked fine. Also after reading online the recommended way to install gems is via source, I went ahead and did it that way.
To get around the mysql error I posted earlier I installed it successfully using.
apt-get install mysql-server libmysqlclient15-dev libmysql-ruby1.8
gem install mysql
My test shows it now has mysql:
irb(main):002:0> require 'mysql'
=> true
I have rails running now, but I wanted to see how the install script sets up Apache2, Mongrel etc..
According to my hosting company they don't over-subscribe but I can't verify it.
Yep, I have also ran into the same error before. Doing an apt-get install ruby1.8-dev was the solution.
I'm having a slightly different problem with the MySQL driver on Debian Etch w/ Virtualmin Pro 3.47.

Running a second time without the MySQL setup options yields:

Rails setup failed :

From a post on installing ROR on debian:
http://daniel.lorch.cc/docs/rails_install_debian/
"extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)"
This probably means that you forgot to install the ruby1.8-dev package. Just do an apt-get install ruby1.8-dev to fix this.
so... Missing dependency?
