The first error is dyld: Library not loaded: /opt/local/lib/libjpeg.62.dylib An easy fix is: post-destroot { ln -s libjpeg.dylib ${destroot}${prefix}/lib/libjpeg.62.dylib }

I found [http://www.blender.org/forum/viewtopic.php?t=15333 this page] which implies there are dire consequences of creating such a symlink, but does not say what they are.

The next problem is that the current version of ${prefix}/lib/libjpeg.7.dylib is 8.0.0 while the old ${prefix}/lib/libjpeg.62.dylib has a compatibility version of 63.0.0. Since 7.0.0 < 63.0.0, an error ensues.

Has anyone contacted the developers of libjpeg to see what the heck they were thinking? :) -- Ticket URL: <http://trac.macports.org/ticket/20193#comment:6> MacPorts <http://www.macports.org/> Ports system for Mac OS

It doesn't matter that 7 is less than 63, it only matters that it's different. Different compatibility version means dyld barfs, there's no lessthan/greaterthan check.

I was under the impression that that was exactly the point of having a compatibility version -- that a less-than/greater-than check was performed. The Fink project's documentation [http://www.finkproject.org/doc/porting/shared.php#version says it is so]: dyld generates a run-time error and terminates the program unless the loaded library version is equal to or newer than the one used during linking This capability is demonstrably at work in tickets like #20959.

The new compatibility version is fine (much more sane), but we will need to bump the revision on every port that depends on jpeg. As far as I can tell, it's API-compatible, but it will still require clients to be rebuilt.

So, can we do this? Or is there something else preventing the update to jpeg 7? -- Ticket URL: <http://trac.macports.org/ticket/20193#comment:8> MacPorts <http://www.macports.org/> Ports system for Mac OS
