AFAICT, if you have a global "tk" USE flag, you can not have 1.8
installed at the same time as 1.9 or 2.0.

I understand that portage defaults to installing multiple versions (of
Ruby, Python, and probably other stuff). What I don't understand it
_why_. If none of the ebuilds specify q version, then they
presumably will work with any availble version -- so why not just
install one version?
