Created attachment 385104 [details, diff] ebuild fix Looks like qmake can't find pro file. It works fine if directory name will be changed from e.g. "qbs-1.3.0" to "qbs". Tested with qt-5.3.9999 and qt-5.4.9999. Adding "qbs.pro" to qmake arguments list fixes build for qt5 and works well for qt4. Patch attached.
eqmake5 doesn't have the additional logic of eqmake4 to disambiguate between multiple .pro files in the working directory. In this case there are qbs.pro and static.pro so qt5's qmake doesn't know what to do if called without specifying the .pro file on the command line. Fixed in cvs, thanks for reporting. 19 Sep 2014; Davide Pesavento <pesa@gentoo.org> qbs-1.3.0.ebuild: Fix build with USE=qt5. Patch by Alexander Akulich in bug 523218.
