need help in installing Blacklight

[Yongming Wang]

Dear Blacklight community,

I'm a newbie. I'm following the Quickstart Instruction from http://projectblacklight.org and have successfully installed Ruby (1.9.3) and Rails.

When I came to step 2 of Install and Use section, after issuing the command "$bundle install" I got the following error:

......
Installing rack-ssl (1.3.2)
Installing json (1.6.5) with native extensions /usr/local/lib/site_ruby/1.8/rubygems/installer.rb:483:in `build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

Gem files will remain installed in /home/yongming/.bundler/tmp/2382/gems/json-1.6.5 for inspection.

I ignored the error and went on to next step "$gem install devise" but got the following error:

yongming@ubuntu:~/my_app$ gem install devise
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /usr/lib/ruby/gems/1.8 directory.

Obviously I can't continue now.

(I have to admit that a few months ago I tried to install Ruby but failed. Maybe I messed up with it. It seems that I have both Ruby 1.8 and 1.9. If that's the case, how can I clean up?)

My server is Ubuntu 10.04 Server LTS x386 32 bits.

Thank you very much in advance for your help and advice.

I'm pretty sure that this is the next step:

sudo apt-get install ruby1.9.1-dev
