Thanks!

I am not introducing that particular flag, so it must be set by setuptools?
What version of setuptools are you using?

Best wishes,
Andreas

you can use

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

it's something about the new xcode treating unrecognized commands as errors

Sorry, I thought I'd reported the workaround that I found on stackoverflow 
22313407:

Currently to install on Mavericks it is necessary to set environmental 
variables so that unused arguments are ingnored:

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

…and then run as root user with –E flag so envs are recognized:

sudo -E python setup.py build

This worked for me.
