Now need to get MySQL installed. I am having the following trouble  
installing

sudo gem install mysql – --with-mysql-config=/usr/bin/mysql\_config

ERROR: Error installing mysql:  
ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 extconf.rb --with-mysql-config=/usr/bin/mysql\_config  
extconf.rb:10:in `require’: no such file to load – mkmf (LoadError)  
from extconf.rb:10

Gem files will remain installed in  
/usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.  
Results logged to  
/usr/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql\_api/gem\_make.out

Any ideas?

This error means you are missing ruby development libraries needed for  
compilation.

apt-cache search ruby | grep dev

sudo aptitude install libmysqlclient15-dev

(or whatever version the libmysqlclient is at for your system)
