Try typing gcc and see what you get?
You should find that configure will error if you've not got the correct
things installed, however I have found it misses one dependency (or used
to), so you may find that it configures but fails to compile, it's just a
case of working out which library it's not finding and installing the
package for that though.

That would be a good starting point, yes. The basic steps are just like any
unix software, './configure && make && sudo make install'
It's worth using the configure settings your current build is using as a
However, if you do this you should be aware of any distro specific prefixes
It might be worth installing your own version into a separate directory, so
you can be sure you're not going to overwrite stuff that's already working,
you can do this with --prefix=/path/to/some/other/folder

Yes, this would be a good idea. If you've got the same version, you should
be able to stop your current backend, and run your new backend (as the same
user) without any problems.
Be aware of library dependencies though, if you've compiled from source
simply renaming your new backend executable may still not be using the
shared libs you expect. (use ldd <filename> to check.)Harry
