Yes. Debian / Ubuntu .dep package creation is documented in Getting_Lazarus 
page. I added a .rpm ToDo item under:
  http://wiki.lazarus.freepascal.org/Getting_Lazarus#Build_a_RPM_package

So if someone makes a .rpm package for Fedora / Suse / Mandriva, please share 
the knowledge.
I will not study that now. The svn version installs well enough.
