After upgrading to Snow Leopard, I found my rails and mysql installs to
be completely hosed, so I uninstalled ruby, mysql, and rubygems and
reinstalled them from these instructions:
http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard/

Here's where things are installed now:

$ which ruby
/usr/local/bin/ruby
$ which rails
/usr/local/bin/rails
$ which gem
/usr/local/bin/gem
$ which rake
/usr/bin/rake
$ which mysql
/usr/local/mysql/bin/mysql

My problem is that if I try to run rake db:migrate (or anything with
rake), I get this error:

$ rake db:migrate
-bash: /usr/bin/rake:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad
interpreter: No such file or directory

My .bash_profile is a mess due to many hours of unsuccessful
troubleshooting:

$ echo $PATH
/~/.gem:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/lib/ruby/gems/1.8/bin/:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/bin:/usr/local/bin:/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/opt/local/bin:/opt/local/sbin:/Users/devin/.gem/ruby/1.8/bin

How do I reset my profile to get rake (and everything else) working
properly.
