changing prefix without recompile

[Brian Kurotsuchi <bkurotsu lug ee calpoly edu>]

Will the following sequence of commands work correctly and change the
destination dir:

% cd <some GNOME source dir, like gtk+>
% ./configure --prefix=/usr/local
% make
% make install
% ./configure --prefix=/opt/gnome
% make install 

The reason I ask is that I need to do installations to both places, but my
machine is not too speedy, so recompiling everything hurts.

I want to do this for all the packages past freetype (inclusive).  By that I
mean guile, gtk+, imlib, gnome-code, gnome-libs, libxml...
