2.0.0.beta.19 installation problem

I purchased the beta version of the PragBook yesterday, but didn’t get
a chance to begin reading until tonight. I’m currently stuck on
installing rspec.

~$ sudo gem install rspec --version 2.0.0.beta.19


Thank you for installing rspec-core-2.0.0.beta.19
Please be sure to look at Upgrade.markdown to see what might have
changed
since the last release.



Thank you for installing rspec-expectations-2.0.0.beta.19



Thank you for installing rspec-mocks-2.0.0.beta.19


ERROR: Error installing rspec:
rspec requires rspec-core (= 2.0.0.beta.19, runtime)

I’m a bit mystified because the process begins by installing
rspec-core-2.0.0.beta.19, but ends by telling me rspec-core
(2.0.0.beta.19) is required. I’m running Ruby 1.8.7 on OS 10.6.4 if
that’s of any help.

Thanks,
Craig

What version of rubygems do you have installed? If anything less than
1.3.7, please upgrade. Previous versions had some issues related to
prerelease dependencies, but they’ve all been fixed in 1.3.7.

HTH,
