Created attachment 202304 [details] patch This port requires C++11-compatible compiler to build, so add USES=compiler:c++11-lang to fix build on GCC architectures. Also add LDFLAGS to the linking command so that it links against ports libstdc++. While here, add USES=localbase. Tested on powerpc64 and amd64. Hardware sponsored by IntegriCloud.
