Created attachment 198227 [details] patch Adding USES=compiler:c++11-lang is necessary for cad/librecad to link against libmuparser (GCC7 used for building cad/librecad won't link against libmuparser built with base GCC). Don't add USES=compiler:c++11-lang, that will break building this port for mips*. Tested on powerpc64 and amd64. Hardware sponsored by IntegriCloud.
