Okay, I know this is a really basic problem that any decent sysadmin could answer easily.  Forgive me for bogging down the list with simple questions, but I'm trying to compile MySQL support into ruby 1.6.7 on Mandrake Linux 8.2.  Here's what I get:

[root@www mysql-ruby-2.4.3]# ruby extconf.rb
checking for mysql_query() in -lmysqlclient... no

And then it kicks me back to the command line.  I try to specify MySQL client file locations as further parameters to extconf.rb to no avail.  Can anyone tell me what I'm doing wrong?

Thanks,
Carl Youngblood
