[Rails] Re: Error installing the MySQL Ruby bindings?

[bbqbaker]

Ha, I am an expert at this. well sort of, i spent all weekend trying to
fix a similiar problem. thanks to the people here, i was able to get
everything up and running./

i think the simpliest way to fix this is uninstally ruby, gems, and
mysql. install ruby, install gems, install rails, then run "gem install
mysql". afterwards, install the mysql libraries/control center/mysql
admin, etc...

also make sure you have a c compiler. in ubuntu, its build-essential.
