Typical free/libre software practice when providing packages is to also provide the sources and build scripts at the time the packages were made. Is there a snapshot available of the sources from the day when you issued the Trinity 3.5.11 packages?
Yes. All of that information is available on the QuickBuild system ( https://quickbuild.pearsoncomputing.net/~trinity/+archive/trinity ), but keep in mind that it was built for Debian, and therefore includes Debian-specific patch files. Click on the package name you want to see details for, then look for a tar.gz file. That file contains the source code that produced the binaries listed.
In addition to our current efforts I would like to try building from the 3.5.11 sources. I want to start using Trinity KDE at some point after the stock 3.5.10. The build process might again fail --- I don't know about that because of some of the Debianization that we are troubleshooting now --- but I'd like to try.
That build *will* fail for the reasons you mentioned. 3.5.12 will be released within the next couple of months; wouldn't you rather wait and iron out the remaining build bugs in SVN? Just a thought.
