I installed Rails 2.3.5. Installed mysql 5.1 developer version. Then I  
did gem install mysql.  
I did myapp -d mysql  
I did rake db:create:all  
Get error “The application has failed to start because LIBMYSQL.dll was  
not found. Reinstlling the application may fix this problem.”  
I completely removed mysql. I reinstalled mysql 5.1 developer version.  
The I did again gem install mysql. Same error persists.  
Can someone help?
