For building RPMs, a spec file is already supplied and will be made automatically after ./configure is ran. The spec file expects a source tarball with the following structure:

mysql-administrator/ mysql-administrator/mysql-gui-common/* »
mysql-administrator/mysql-administrator/*

The contents of each subdirectory is the entire source tree for each tool (Windows specific files and source metadata are optional, of course). You must make a tar.gz file and put it in /usr/src/redhat/SOURCES (or whatever is your rpm SOURCES directory).

Then, execute: rpmbuild -ba mysql-administrator.spec

That should build the srpm and rpm files for the tool.
