ruby on rails mac x os lion run server LoadError

Question

When I type the rails server on terminal, I got the following error. I don't know how to fix it. Is any one can give me a help? And I also need a ruby on rails mac os x Lion installation tutorial.

:simple_cms benhuayang$ rails server

this is path for mysql

/Users/benhuayang/.rvm/gems/ruby-1.9.3-p0/bin:/Users/benhuayang/.rvm/gems/ruby-1.9.3-p0@global/bin:/Users/benhuayang/.rvm/rubies/ruby-1.9.3-p0/bin:/Users/benhuayang/.rvm/bin:/opt/local/bin:/opt/local/sbin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

What process did you use to install MySQL? You might be able to do a which mysql from the terminal to get the path. — Ryan

When I've run into this in the past, I've used the following solution.

In the terminal, run:

export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/usr/local/mysql/lib"

Then try running your rails server command in the root of your app. If it works, just put that same command into your ~/.profile so that it runs each time you enter the terminal.

Ryan's solution worked for me when I had the following error after running rake db:migrate, I figured posting it will help with the google search.

rake aborted!
