unistall/remove mysql 5.1.39 from Linux

I have MySQL 5.1.39 on My Linux machine
Now i want to uninstall the MySQL 5.1.39 and install a older version of it
Note: there are no mysql rpm

I believe, there is no uninstall target in the tar.gz.
So, without package manager, you need to manually rm all the files from the 5.1.39 installation.

Probably it is a good idea to look at the install readme file to get an idea on what to undo.

Hi Thanks for the reply.........
