./pm -DPREFIX="/home/dg/" install

(If you do change the prefix, you must supply it whenever you invoke pm,
whether you're installing or just building. And there must be a trailing / in
the path you give it.)
Invoking ./pm by itself will compile it but not install it; look in the bin
directory for an image of the installation directory.
(If you do change the prefix, you must do a `make clean` first, or else the
installed binary will look for its libraries in the wrong place.)
