Created attachment 410400 [details, diff] patch for QT5 sci-mathematics/rstudio-0.99.473 needs the attached patch to compile with QT5. Furthermore it looks like it builds with clang-3.6.2-r100 just fine.
Thanks for reporting. It built fine for me with dev-qt/qtcore-5.4.2. I guess I'm curious what the compiler error was in the build.log. The patch looks harmless though, I'll try it and check it still builds for me.
Wouldn't it be better to patch out the bundled qtsingleapplication? AFAIK that was done for several other applications already.

Yes, thanks for the suggestion. commit 7a45c4dcb255f80d2bc7c891f532bc81a95ecaa8 Author: Mark Wright <gienah@gentoo.org> Date: Mon Aug 31 00:28:31 2015 +1000 sci-mathematics/rstudio: Fix bug 558900, unbundle qtsingleapplication Thanks to Helmut Jarausch for reporting, Franz Fellner for suggesting patching rstudio to use dev-qt/qtsingleapplication[qt5] rather than the bundled version. Remove sys-devel/clang upper bound, thanks to Helmut Jarausch for reporting and testing with clang-3.6.2-r100. I tested it builds with clang-3.7.0_rc3.
