As these are not already available in extra's I assume that there is
a very good reason for this as with no tweaking at all I have just
built the administrator package after installing it with yum localinstall
to satisfy its dependancies and then subsequently the query browser
(this needed a small tweak).
So with a bit of tweaking I have now built both packages and have
as a result of the build process re-packaged sources that build cleanly.
mysql-administrator-1.1.5-1.FC4.src.rpm
mysql-query-browser-1.1.17-1.FC4.src.rpm
as well as the resultig install packages.
These ofcourse are not signed packages nor do they put icons in the
menu's but working icons can be copied to the desktop or panel from
/usr/share/aplications.
