So, if I understand you, if programs were going into /usr/local/bin you might 
want to go into /usr/local/bin/private?

There's a double whammy.  First, you have to look at $mm->{INSTALLDIRS} to 
figure out what set of install directories you're going to.  Then you need to 
figure out what set of install variables this maps to (for example, "perl" 
maps to INSTALLPRIVLIB and INSTALLBIN but "site" maps to INSTALLSITELIB and 
INSTALLSITEBIN).  And for the final insult, you have to expand any make 
variables inside $mm->{INSTALLBIN} yourself.  For example, if a PREFIX is set, 
$mm->{INSTALLBIN} might be '$(PERLPREFIX)/bin'.  MM_Any has a private 
_expand_macros() method you can crib from.

Once you have that, you can modify it to your liking and add a postamble() 
which extends pure_install.

Or maybe Module::Install has something to handle this.

In Module::Build you follow these instructions to add a new install type.
http://search.cpan.org/~dagolden/Module-Build-0.3603/lib/Module/Build/Cookbook.pm#Adding_new_elements_to_the_install_process

Then you call $builder->install_destination("bin") to get the install location 
and modify it to your liking.

I'm sorry, I cannot delete the above MB recommendation in strict compliance
