14 Failures:
mlt mlt++ (both mlt & mlt++ are OK on i686) tdebindings amarok kchmviewer kdmtheme kbfx kima kstreamripper krusader kmplayer (I think this will build -- will have to tweak) kuickshow digikam (libpng15 issue) koffice
I cranked builds all weekend.
I don't build mlt/mlt++ because nothing in the Trinity sources uses those files.
I don't build kbfx because of several breakages (bug report 1065: kbfx FTBFS and fails to build help handbook).
I don't build the separate kuickshow because the same exact sources are in tdegraphics.
I don't have libpng 1.5 installed anywhere and can't confirm the digikam failures.
I don't build kstreamripper because the package builds on only one system here (13.1 32-bit) and fails to build on everything else, including all 64-bit (bug report 946).
tdebindings will not build for me on Slackware Current, but builds on 13.1 and 13.37, both 32 and 64-bit. The oddity is the failure is from ruby and not from Trinity.
tdesdk won't build on Slackware Current. I'll post a separate message about that because you ran into the same failure back in March.
Thus far, no problems building the other listed packages on any of my Slackware systems.
