Right, but then in Fink I can have two packages, libpoppler1-shlibs and
libpoppler2-shlibs when the soname changes, so that we provide a compatible
library until applications update.  We follow the debian model in that respect.

As long as you can have /path/to/libpoppler.1.dylib and
/path/to/libpoppler.2.dylib coexist peacefully, it's fine.  If you change ABI
and don't up the soname to 2, that's when there are problems.

Honestly, I believe that should work, but I don't know the specifics enough to
be able to say for certain.  Hopefully I can get Peter O'Gorman to chime in,
he'll have a better idea how it will work on darwin.
