I typically avoid installing anything into /usr/local, because my
experience with that is you end up wanting to remove half of
whatever you have there.

There are basically two approaches:

 A) Install everything into some place into /opt, have shell
    aliases/scripts that set up all the environment variables
    appropriately.

    This is how build scripts like 'jhbuild' or 'garnome'
    work, generally.

 B) Just write over the system libraries, using
   
    ./configure --prefix=/usr --sysconfdir=/etc

I generally take course B), as just a whole lot simpler;
Plus, it forces me to not break things too badly :-)
