MySQL Install: ERROR: Failed to build gem native extension
I'm trying to get MySQL installed to the latest version due to some installation going wrong somewhere along the line. I run the command gem install mysql and I receive the following:
Building native extensions. This could take a while... ERROR: Error installing mysql: ERROR: Failed to build gem native extension.

I've searched, and tried a whole host of things, from installing specific versions to trying to reinstall ruby without any luck.
Any ideas where I may be going wrong?

EDIT: I installed XCode off my Snow Leopard DVD and the error just changed slightly to the following:

doing "which mysql" on the command line returns nothing, which means it's not recognizing it. I also installed the MySQL system preferences option, and I can't stop MySQL from running. Now I'm completely stuck as what to do!
EDIT EDIT
I've just completely reinstalled MySQL using this guide http://hivelogic.com/articles/installing-mysql-on-mac-os-x
Unfortunately this didn't work either, I still receive the same errors. I can't even do mysql -uroot at the command line, I get the error of:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
So I think I've tried everything.
**SOLVED*
Sorry guys, the reason for this not working was because of the MySQL paths. I've blogged on it here: http://www.kieransenior.co.uk/2010/02/mysql-cant-connect-using-ruby-on-rails-mac-os-x-snow-leopard/
Solution 1:
On Debian (or Ubuntu) systems, just install libmysqlclient-dev package using:
sudo apt-get install libmysqlclient-dev
and then:
gem install mysql
It will be installed without any error.
Solution 2:
Installing the mysql gem on OSX
in a terminal.. First do a ‘locate mysql_config’ and then replace the path in the following command with where that file is.
$ sudo gem install mysql -- —–with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions. This could take a while…
