Rake error

I posted this on Ruby Talk but then I realized I probably should of
posted it here instead...

I receive this error when running a rake command:

$ rake db:migrate
(in /Users/jeremy/rails/depot)
dyld: NSLinkModule() error
dyld: Library not loaded: /usr/local/mysql/lib/mysql/libmysqlclient.
15.dylib
  Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/
mysql.bundle
  Reason: image not found
Trace/BPT trap

I'm working with the book "Agile Web Development with Rails" and even
though it discusses many possible errors, none of them relate to this
one. Also, my database.yml file seems to be correct so I don't think
that's the problem.

Well I discovered the diagnoses but not the cure. My "libmysqlclient.
15.dylib" file is located in "/usr/local/mysql/lib" instead of "/usr/
local/mysql/lib/mysql". I opened up the "mysql.bundle" file in vi but
it was complete chaos. I could see where to make the change but it
didn't look safe to edit the file. What do I do?

I found the answer on Google.
