rails s error os x 10.8.4 rvm

Question

I am just installing ruby / rails / gems ect. I installed rvm and I received many errors similar to this post, not sure if it is related. I believe I resolved the issues by installing ruby docs.

After installing everything I was able to create my project with the following command, which appeared successful

rails new simple_cms -d mysql

I then ran the following command and received the following errors,

jg$ rails s

I had experienced a similar issue. Adding a symlink similar to the following worked for me:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

Please give this a try.
