I know that Debian testing has no problems, but I am using Debian stable (Lenny).
By the way, if I try to compile from source gives the following error after a while:
qmake -o Makefile.qt pictureflow.pro
QMAKESPEC has not been set, so configuration cannot be deduced.
Error processing project file: pictureflow.pro
error: command 'qmake' failed with exit status 3
What does that mean and how can I get around it?
