I have a problem installing the lxml in my mavericks machine.
I tried all possibilities by installing the prebuild binaries using
normal pip
pip with static deps
and Building
Current version in normal model
Current version with static deps
Older version in normal mode
Older version with static deps
and always end up in this error.

I am totally struck here. It seems this is something to do with the version conflict with gcc or libxml. But i could't figure out what. Any help much appreciated.
SOLVED
As per this SO post clang error: unknown argument: '-mno-fused-madd' (python package installation failure), this can be fixed by setting up this following env variables
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
I am sure that by that that you sorted it out, but in case someone else needs it, install XCode and command line tools and just run
pip install lxml
It will work, may take a little time.

I had the same problem, and I run conda install zbar, after that, the error disappeared.

The issues is down to a recent update to xcode 5.1:

Anyone had the same issue and know of a workaround that works in your virtual env?
I wrote the post on your first link. I am not 100% percent sure but I think the problem lies with the use of sudo. The variable is set under your user, while the pip command is elevated to root privileges, i.e. is executed under another user. Try to do the above logged in as root user from the start, without sudoing.

how to install PIL on mac os x 10.7.2 Lion
I'm trying to install the latest version of PIL (1.1.7) on Mac OS X Lion (10.7.4). I generally just use PIP and the following command:
sudo pip install package_name
However, I'm getting an error message for PIL, as it is refusing to cooperate with me.
