Then something must have changed with your tqtinterface install, because I have always handled it manually there:
# Create and install ld.so.conf.d file install -d -m755 $pkgdir/etc/ld.so.conf.d/ echo ${_tdedir}/lib > $pkgdir/etc/ld.so.conf.d/trinity.conf echo ${_tdedir}/lib/trinity >> $pkgdir/etc/ld.so.conf.d/trinity.conf
ldconfig is then called by the post-install script.
No, I just never got the memo.
