Install cvxopt on mac failed

I tried to install cvxopt on mac OS X 10.9.2 (Mavericks)

Here is the output:

Any suggestions ?

I'm also using 10.9.2 with the same compiler, but I don't get the error. 

It looks like it's not a problem with CVXOPT:

Thanks for the link. It worked with that solution.

What I did is:

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

sudo -E python setup.py install
