37 Title Qt 4.5.2 default USE flag changes
38 Author Alex Alexander <wired@g.o>

41
42 Qt version 4.5.2 has significant changes in the USE flags enabled by
43 default.
44
45 When upgrading, make sure you check and re-enable any USE flags you
46 need.
47
48 Depending on your system and installed packages, you might hit an issue
49 where Portage is getting confused by this USE flag change, trying to mix
50 old 4.5.1 ebuilds with new 4.5.2 ones, resulting in blocks.
51
52 If this happens to you, please add the offending USE flags (usually
53 'qt3support' and 'dbus') in your USE= or switch to a desktop profile
54 (eselect profile list). Check this post [0] for more details on this
55 issue.

62 I have this in my USE flags and I didn't run into this that I recall.
63
64 qt3 qt3support qt4
65
66 I think they are planning to remove qt3 in the future. I'm not sure how
67 close that future is tho. I think qt3support is the key here.
