Created attachment 201276 [details] patch to Makefile devel/libunwind is only available for x86. This blocks a great many ports from building on e.g. powerpc64. This patch conditionalizes that dependency.
Thank you very much. I will merge the patch soon.
As I see now all supported versions of ruby do now record libunwind as dependency. The conditional LIB_DEPENDS in iroffer is no longer needed on all architectures.
