I've used the version comparing code from prt-get (a bit tweaked) to create a standalone app called 'vercmp'. Along with a shell script I put together called pkgupdate (does this interfere with any other tools that i don't know about?) you can for example have a cron job which will scan your crux repo, reading in the Pkgfiles and attempt to find the latest version from the source url given. It's not 100% because some projects like to change up their versioning syntax... but it works pretty well for me. I think the only thing left is to make it create md5sum files. Perhaps attempt to do a full package build to confirm it'll work. My repo was listed on the ports page but it seems to have disappeared so I'll reregister. The ports are at http://www.landofbile.com/crux_ports Feedback, enhancements welcome.
