Hello, I have updated the lastfmplayer-1.4.2.58240-r1.ebuild to use the split Qt4 dependencies (See tracker bug #217161). It seems to work fine on ~x86 with only qt-core, qt-script, qt-gui (USE="cups glib tiff") and qt-sql (USE="mysql sqlite") installed.
Created attachment 153587 [details] lastfmplayer-1.4.2.58240-r1.ebuild for split Qt4 ebuilds
Fixed in CVS
