this bloody hack makes install.rb handle user defined bindir (-b) and
auto-shebangifies any ruby programs found in the ./bin dir while installing
using the path to the ruby interpreter used for the install or the one named
with the -r switch.
essentially this allows you to write your scripts as in
#!/my/crazy/local/path/to/ruby
...
and they will be installed as
#!/users/path/to/ruby/used/with/install.rb
#!/my/crazy/local/path/to/ruby
...
eg. the user's path to ruby will be added to the program and your script
appended vebetim.
i don't know who originally wrote install.rb or where i got it so thanks to
original author and here's the hack:

require 'tempfile'

$archdir = File.join($libdir, CONFIG["arch"])
$site_libdir = $:.find {|x| x =~ /site_ruby$/}
$bindir = CONFIG["bindir"]
