Problem installing MySQL with gem

Hello there.
Iam new to Rails and yesterday started the procedure of
installing/updating my ruby, rails, gem and mysql so that i can start
learning the language.
Im on Macintosh Snow Leopard 10.6

I issued the following commands on my terminal:

$ ruby --version
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]

$ gem --version
1.3.7

(after updating it from 1.3.5)

$ rails --version
Rails 3.0.1

(after updating it through gem , following the instructions from the
rails website)

I installed the latest MySQL 32bit

Also i issued the following commands on my termilan:

$ which ruby
/usr/bin/ruby

$ which rails
/usr/bin/rails

$ which gem
/usr/bin/gem

$ which mysql
/usr/local/mysql/bin/mysql

And i've set the PATH: (.bash_profile)
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

Having said all that i tried to install mysql through gem with the
following command on the terminal:

$ sudo gem install mysql

and the result was this:

$ sudo gem install mysql

Apparently the mysql plugin is not installed or not working with rails.
How can i fix this?

I have no experience with any of these.
Im trying to have all those ready so i can start studying/learning
rails.
Thank you

It is installed. Just ignore everything after:

thank you for your answer
so why can't gem install the Ri and Rd documentation ?
arent they necesary?

I am not sure, but I generally view the documentation online anyway personally. I doubt it is critical for you to have either installed for the gem to work properly.

ok i see
well, i've been trying for 4 hours now to find my way with mysql and
rails with no success. Seems like it can't connect to mysql at all
through the rails commands (rake, etc...)

Switched to sqlite3 to give it a go and it worked right away.

So at the moment i'll stick to sqlite3 so i can start learning rails
and not spend days trying to make mysql work.

I got a bit disappointed to be honest.

It may help if you copy and paste the errors. It should work out of the box, if nothing else.

Looks like you don't have libmysql-dev installed.

However, I'd strongly urge that you use PostgreSQL instead of MySQL.
It's a much better DB.

Best,
