A nice alternative to manipulating $PATH or other shell
things for each package is to use symlinks in /opt/bin and
/opt/man.

  $ su
  # cd /opt/bin
  # file foo
  foo: symbolic link to ../foo-1.2.2/bin/foo
  # rm foo
  # ln -s ../foo-1.2.3/bin/foo
  # cd ../man/1
  # rm foo.1
  # ln -s ../../foo-1.2.3/share/man/1/foo.1

It's usually not too hard to use shell loops with "find" to handle
multiple files.
