Use the PREFIX option. You can, for example, create
~/perl5 and let it go from there. The problem you'll
have without acess to some area that perl is looking
for when it starts up is having to use

	use lib "$ENV{HOME}/perl5/lib";

in all of your code. Another approach is to symlink the
necessary lib's from ~/perl5/lib into the current working
directory -- since perl normally has '.' in @INC. Problem
there is that the lib's will be at the end of your search
and won't override out-of-date lib's in the main dir's:

Characteristics of this binary (from libperl):

You can get around this with FindBin::libs (see example in
the POD for it), but you'll have to convince the Powers
That Be to install FB::libs into one of perl's hard-coded
locations (it'll normally go into /.lib/site_perl/X.Y.Z/FindBin).

You can also use the -I switch at the command line to include
more dir's, but this precludes much #! code.
