I've done something similar in shellscript: wip/apstget.

It's not yet finished and needs lot of testing, btw without
caching anything a shellscript calling '$MAKE' is really _slow_.

It have a "relink" action that creates symbolic links to the target
directory to the newest one when a new library is installed.

It works, but ABI problems are not handled. It just allows you
to perform a safe "upgrade" or a package upgrade with relink
libraries on rev dependencies.

It also notifies you about the PKG_OPTIONS flags before starting
to install.

So imho the right way to skip the ABI problems is to mark packages
with some kind of abi-version-compatible-range. Or something like
ABI version (btw, it can try to interpret the version number changes
(major number implies completely rebuild of deps). Or something
similar.
