MySQL 4 RPM question..

[WipeOut]

Hi,

Following up on my prevoius questions about using MySQL 4..

Somone pointed me to this page..
http://fedoranews.org/contributors/tony_smith/mysql/

Its a nice easy to follow guide but I am still unsure why the RPM's 
provided by MySQL can't be used on FC1..

I mailed the author but did not get a response..

Would someone far cleverer than me plase explain why the MySQL RPM's 
can't be used and why I have to build them myself on FC1??

Thanks dudes!!
