Please update the Qt 4 dependencies. See tracker bug #217161.
Hello, I have modified the original ebuild of net-misc/vidalia-0.0.13. It seems to work fine for me on ~x86 and qt-4.4.0, I have tested it with only qt-core, qt-script and qt-gui installed and a small amount of UISE flags (+cups +glib +tiff +-debug). However, if debug USE flag is enabled, it checks if qt is installed with debug use flag, and now this flag can be set for every split package separately. I only added the check for qt-gui, but it should maybe also check for debug flag in qt-core.
Created attachment 153577 [details] net-misc/vidalia-0.0.13 ebuild for split qt4
Fixed with 0.1.7 ebuild in CVS.
