Attempting to build icu-58.2 on MacOS Sierra with clang-3.8.1 fails with: Undefined symbols for architecture x86_64: "_icudt58_dat", referenced from: openCommonData(char const*, int, UErrorCode*) in udata.o ld: symbol(s) not found for architecture x86_64 x86_64-apple-darwin16-clang-3.8: error: linker command failed with exit code 1 ... also noting that gcc doesn't grok the '-std=c++14' which the ebuild force-sets (although there's a bug for this in the main tracker) and using the platform compiler suite via Xcode command-line tools breaks more even earlier. Dropping the c++14 line from the ebuild and attempting to build with gcc throws more errors - but ultimately fails in the same place with the same error, with either binutils-apple-6.3 or binutils-apple-7.3.1.

which clang-3.9.1 this installed fine for me.
Created attachment 461902 [details] build.log for failing icu-58.2 package Build log for failing icu-58.2 built with clang-3.9.1 on MacOS 10.12.2
Hmm - still broken with exactly the same error with clang-3.9.1 :( Build log attached... (In reply to Fabian Groffen from comment #1) > which clang-3.9.1 this installed fine for me.
current state of the tree doesn't exhibit these problems
