Ruby: No such file to load -- ubygems (LoadError)

I deleted the contents of directory site_ruby and I was getting that error message. After some googling found Rich Kilmer's reply

"You have installed rubygems and set the RUBYOPT variable. This is the
downside to using the RUBYOPT :-(

Just unset that variable and then you should be good to go."

Thanks Rich, that fixed my problem.

rmagick headache on mac os

Finally resolved the rmagick installation problems. The actual problem was not rmagick itself but a custom script in my project.

I found the RMagick install script for Mac OS X - Version 0.2.0
on rmagick installation faq.

/opt/local/bin/ruby: bad interpreter:

I was getting the weird ruby bad interpreter error message after I deleted everything under site_ruby directory. I was working on getting the rmagick working on my laptop. I resolved the problem by reinstalling the Ruby 1.8.6 and Rubygems 0.9.2.

Capistrano Concepts

Chris Selmer's Capistrano Presentation from the April 5, 2007 DCRUG
meeting is very good.

The Rails Edge conference had discussion on the material
covered in this presentation, but this presentation connected all the
dots for me.

Copying to the clipboard in UNIX

You can send any output to the clipboard by using pbcopy. For example: history | pbcopy will send the output of history command to the clipboard. You can just paste it in email or other document. Very nice. pbpaste will paste the contents of the clip board.
