Module::Build has the moral equivalent in install_base.

	perl Build.PL install_base=~

This is different from PREFIX in that its not going to try and guess how
you want things installed based on your system installation.  It's just
going to plop things into ~/bin, ~/lib, ~/man, etc...  This is much
saner and easier to predict than PREFIX.

Unfortunately, this often means MB will put things in a slightly different
location than MM does.  You can exactly control where MB puts things (as
you can with MM) by passing various explicit install_* parameters so it
matches exactly where MM puts its stuff.

Meanwhile, MM is going to have INSTALLBASE added to it to emulate MB.
Also there are plans afoot to have a .modulebuildrc file which stores your
default Build settings so you don't have to keep passing them in on the
command line.

MB has the capability of generating a Makefile.PL wrapper 
(see Module::Build::Compat).  Unfortunately this does not understand
PREFIX, the logic is too hairy to emulate.  Ken and I are working on getting
that working.
