[Comment 2 Daniel Scharrer 2013-11-04 01:23:29 UTC]

I get this as well with dev-qt/qtcore-5.2.0_beta1 - used to work fine with dev-qt/qtcore-5.1.1 but that has been removed from the overlay along with the version bump in commit d97e6d5d354e7d73a941c66340b9dfe75ee257f0.

Interestingly, this prevents emerging =dev-utils/cmake-2.8.12 even with USE='-qt4 -qt5'.

Relevant diff between qtcore-5.1.1 and 5.2.0_beta1

[Comment 3 Franz Trischberger 2013-11-04 07:59:26 UTC]

Thx for the research! I applied the upstream fix and cmake now runs without an error.

[Comment 4 Davide Pesavento (RETIRED) 2013-11-06 18:55:54 UTC]

Already fixed upstream for 5.2.0_rc1
