We have a way to make it not too user hostile:

if (set of packages that have to be updated) include another
manually-installed package, ask for confirmation.

The way it works it holds up is we major bump all the other libraries
depending on it too, so no conflicts are going to happen.
We have the ability to represent this within pkgsrc but uhmm big project
and I think joerg will have some esoteric scenario he picks up where I
can't rename bl3 PKGREVISION -> SONAMEBUMP and get the right thing.

Certainly, with libGL in netbsd this has been a problem because things
are expected to hard-code "dlopen" (it even got documented as
the way to do it ?!?!?!)
