For some reason I can't get mysql gem installed. I have the
libmysqlclient
and mysql-server and mysql-client installed, but it doesn't work. I am
running ubuntu 8.10. Am I missing a required package I don't know about?
What am I doing wrong?

Here is the output:

joey@lab:~/Projects/rets$ sudo gem install mysql
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:

When I try to use the --with-mysqlclientlib conf option, I get this
output:

joey@lab:~/Projects/rets$ sudo gem install mysql --
--with-mysqlclientlib

see how it changes from -lmysqlclient to -ltrue?
