No, Debian's path does not include /var/lib/*/bin - The default paths,
set by /etc/profile, read:


if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/games"
fi

Requiring rubygems does not change it, even from within Ruby:

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> system 'echo $PATH'
/usr/local/bin:/usr/bin:/bin:/usr/games
=> true

So I think this bug does not bite us.
