I recently updated my current again but only just realised that my dvdrip dependency for ImageMagick was not working - ie. dvdrip didn't appear to find ImageMagick. The current installed version is 6.5.1.

I dug up a current from about a month ago and install the 6.4.3 version from that and now dvdrip finds ImageMagick fine.

Could this just be a matter of rebuilding transcode with the newer ImageMagick or a problem in the latest current package?

dvd::rip and transcode are not part of Slackware, if you have them on your system you must have either built them from source or downloaded a binary package built for a previous Slackware release.

In either event, there is no guarantee on the part of Slackware that software outside of the included packages will work, so it isn't an issue with Slackware. You need to rebuild the packages, or if they were binary, try and find somebody who has built one for -current.

I understand the possibility of packages breaking as a result of other packages bein upgraded - I was just wondering if anyone knew what might be diferrent in the latest IM package that may have cause an issue with dvdrip?

ImageMagick is one of the rogue lib projects that tends to change its API from one small release to another without much warning. x264 and ffmpeg are some notorious other ones. That's the main reason many projects are moving to GraphicMagick, a fork of ImageMagick that plans to have a stable API.
transcode, used by dvd:rip for almost everything, is built against ImageMagick to extract single images and also to be able to create videos from image lists.
The IM upgrade has probably changed the API in such way the transcode module cannot work anymore. You have to rebuild transcode. The rest should be able to stay the same.

Interesting news - the latest imagemagick package works fine again.
