Yeah, that should be an INSTALL note. You can not delete them as the
user may have an old gpsd laying around.  I commonly rename gpsd to
gpsd.OLD just uncase the update fails.

IMHO: that is the proper thing to do.  Other packages may be linked
to the old libgps.so.

Gentoo has a program (revdep-rebuild) that checks for old versions of
libraries that are still used.  It rebuilds what it can and warns abou
the rest.  Very helpful.
