Have you had a chance to fire up a Trinity session yet to ensure that it works properly?
Nope. I was hoping to get all of the core packages built before trying.
OK, sounds like a plan. Working on kdepim now; looks like the libical API changed slightly in 0.46.
Regarding libcaldav and libcarddav, both will build with this sequence:
./autogen.sh ./configure --prefix=/usr --mandir=/usr/share/man make make install
