libkdeedu/extdate for kde-4 now compiles. I had to disable the
ExtDateTimeEdit class, because making it work is going to require a
major reimplementation. Since we need this library in order to work on
the rest of KStars, I don't want to let this minor widget stand in the
way.
libkde/kdeeduplot already compiles, but there is still a compile problem
with libkdeedu/kdeeduui (specifically, the glossary widget that we use).
I will see if I can get that library compiling as well, then we can
finally start porting kstars itself.
