Ubuntu 9.10:: Error: uninitialized constant MysqlCompat::MysqlRes

Hi, I've seen configuration issues involving this error message when running rake under Mac OS 10, where it seems to be associated with a bad link.

I've just got the same error, running Ubuntu 9.10. I have the following packages installed mysql Ver 14.14 Distrib 5.1.37, for debian-linux-gnu (i486) using EditLine wrapper mysql-client version 5.1.37 rails 2.3.5 gem 1.3.5 ruby 1.9.1

full error message is as follows:

steve@default:~/maudit/test$ sudo gem install mysql [sudo] password for steve: Building native extensions. This could take a while... ERROR: Error installing mysql:   ERROR: Failed to build gem native extension.

Any ideas?
