Polish KDE SC versions FLAVORs handling.
Use ${MODKDE4_DEP_DIR} instead of x11/kde4 everywhere.
Get rid of ugly := dependencies hack.
Remove TODO, KSirk builds fine with new system resolver.
Unbreak (hopefully) Ruby in KDE 4.10.2. Using 1.8 everywhere, until
kross-interpreters gets support of Ruby 1.9.
Use MODKDE4_FLAVOR instead of MODKDE4_VERSION in Makefile.inc files
of KDE SC ports. Add a note that other ports should not touch this
variable.
Adapt kde-release-helper to new world order.
