I was trying to install zbar on my Macbook.
When I execute command pip install zbar (after brew install zbar） Exception is thrown as below:

There is a similar question, However the answers are not helpful in my case.
I also tried another way to install according to this link
However the same error occurred when I type python setup.py install

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

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 am unable to install MySQL-Python on Mavericks with sudo pip install MySQL-Python
I did
export CPPFLAGS=-Qunused-arguments
and
export CFLAGS=-Qunused-arguments before running the command, but I still ran into this same error.

You probably need Xcode's Command Line Tools.
Download the lastest version of Xcode, then go to "Preferences", select "Download" tab, then install Command Line Tools.
I followed the following procedure:
1) $ sudo pip install psycopg2
This gave me the following error

2) Then I searched on web for installing llvm-gcc-4.2 and from this http://developer.apple.com/library/mac/#releasenotes/DeveloperTools/RN-llvm-gcc/_index.html
got to know that I need to install Xcode
Also from this psycopg2 installation problem on OSX Lion I came to know that I can install psycopg2 via macports but then from this http://www.macports.org/install.php came to know that I need xcode again.
3) Finally I tried to install Xcode from apple store, it downloaded 1.6 gb file and after that says that it is now installed on my system. Here is the screenshot of the same
![macports installed image][1]
4) And then I tried to install macports via the dmg file available at http://www.macports.org/install.php but it says that xcode not yet installed on my system. Here is the screenshot of the same. ![when trying to install macport, xcode not installed message appears][2]
There is an additional detail missing here. In Xcode 4.3 and higher you need to install the command-line tools as a separate step. You need to do this in order for the script to initiate the call to the command line version of llvm-gcc-4.2
Go to Xcode > Preferences > Downloads > Command Line Tools Install.
The problem most likely is that you only downloaded the Xcode INSTALLER from the App Store. You now need to run the installer to install Xcode.
