Tim, Serghei, All:
I ran into an earlier build error with amarok that indicated a '-fpermissive' problem, so I added the flags Baho had set in other files that let amarok build further until I hit the undefined reference to `Amarok::aboutData' error.
Why the new need for:
CFLAGS=${CFLAGS}" -fpermissive" CXXFLAGS=${CXXFLAGS}" -fpermissive"
in the build?
