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:

[email protected]:~/maudit/test$ sudo gem install mysql

Any ideas?
