In general, library version numbers change because the libraries are incompatible, and if you force the issue with libmap (or its cruder cousin, ln -s) you will begin to enumerate the ways in which they are not compatible when your application crashes or misbehaves. Using libmap should not be thought of as a solution unless you know what you are doing and can verify that it is safe on a case by case basis. This may sound like pedantic advice, but I have dealt with many mailing list users who are all up in arms about "how crap the ports collection has become..nothing works any more...freebsd is dying...and *mumble mumble* when I botched an upgrade a few months ago I symlinked all the missing libraries to new versions...don't do that you say? But that cannot possibly be related...oh wait it was, okbye." Kris
