Hi  
I am pretty sure that this is a common nuby problem but I cannot figure  
it out i try to run scfaoldong and get a error “Before updating  
scaffolding from new DB schema, try creating a table for your model”

I have mysql set up and created the tables etc.

# Get the fast C bindings:

# gem install mysql

# (on OS X: gem install mysql – --include=/usr/local/lib)

# And be sure to use new-style password hashing:
