Unfortunately the build logs won't help you, but
if you have
access to your build directory look for the tdecore/tde-config.cpp
file (note: NOT the tde-config.cpp.in or tde-config.cpp.cmake files) and see
what follows "xdgdata*" in the source code.
grep xdgdata $TMP/tdelibs.build/tdecore/tde-config.cpp
"xdgdata-apps", I18N_NOOP("XDG Application menu (.desktop files)"),
"xdgdata-dirs", I18N_NOOP("XDG Menu descriptions (.directory
files)"),
"xdgdata-apps", "/opt/trinity/share/applications/tde",
"xdgdata-dirs", "/opt/trinity/share/desktop-directories",
I'm building new test packages now and will report again soon with the installation
results and Konqueror behavior.
