So one (perhaps small) issue with this is that if there are versions

    foo at 1.0
    foo at 1.0.0.1

then "foo at 1.0.0" will match the latter, not the former.  That is, it means
you have to know the version space immediately following the version you
want to install so that you don't install a version you don't want.  Or you
could add some "sufficiently large" number of .0s to "make sure" you don't
run into the problem: "foo at 1.0.0.0.0.0.0.0.0.0.0.0" (hopefully that's
enough).  I don't know how compelling that is, but I'm pretty sure I've
seen versions with two consecutive .0s before.
