Well first, do not mixate %_prefix, the top level of most software 
(except /etc, /var) and the Prefix tag which allow to rpm change to evilly 
change some parts of files path to install the software in another tree than 
the default.

Does the relocation is a good thing and doesn't will breaks you software ?
If change on the fly the path of some files make the application not working 
(because it want files in /usr/share and not elsewhere), forget the Prefix 
tag. On mandriva (was Mandrake and Conectiva), no package are relocatable, 
and this does not make our distro better or worst.

But well, as rpm is dedicated to properly install/erase software in a cleaner 
way, why do want you want to put it in /usr/local ? useally /usr/local is 
used for sotfware installed w/o rpm.

Finally, if you really want to put the software into /usr/local inside your 
rpm, redefine %_prefix, %_sysconfdir, %_var, ect... at beginning of your spec 
or in your ~/.rpmmacros.
