i’m rather new to rails, and having a bit of trouble. i keep receiving  
an  
error “This application has failed to start because LIBMYSQL.dll was not  
found. Re-installing the application may fix this problem”.

here is the environment i’m using:

wamp server 5  
ruby 1-86  
ruby gems 0.9.4

i created the rails app by running

c:\ruby\> rails depot

no problems here

then i created a database using phpmyadmin called depot\_development

i edited the database.yml file to use the correct database name, root  
for  
user, and password is blank

when i run

rake db:migrate from the application directory, that is where the error  
comes from.

any help would be greatly appreciated

thanks,  
jason
