Apple installs nothing into /usr/local/ on a vanilla machine, so anything there 
is yours - it functions the same as /opt.

Other things, such as sed, flex, and pcre, are already present in /usr, 
supplied by Apple, but not compatible with the Octave build process. If you 
install your versions in /usr/local then the Apple versions will still take 
precedence and build will still fail. I recommend overwriting them with 
--prefix=/usr, but if you wanted to preserve the Apple versions you could 
install them to /usr/local (the default) or elsewhere, and manage the search 
order yourself.

Furthermore, if you want to remove something, sometimes 'sudo make uninstall' 
works, otherwise you can try 'sudo make install' and then delete all the files 
with the new timestamp.
