    Unfortunately not all open source software behaves as nice as
this... (Actually my experience is on the contrary.)
    :) As trivia, even pacman doesn't support install-docs, or
install-libs target.

    So a simple solution to this problem, that can be applied as a
recipe for most packages, would be: just let the package install as it
wants, and then we'll trim off what we don't want.
