Hi
I haven’t got a clue how that argument gets in there, probably is some Python build issue rather than umemcache

This is due to a change in clang. It'll basically start throwing errors upon seeing unknown (usually GCC specific) command line arguments, while previously it just ignored them. You can temporarily disable the error by setting ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future. So to install something via PIP (this affects pretty much any C extension):

env ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install umemcache
