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.

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.
