There are many users of Python today that got used to the conda distribution of Python, provided by Anaconda. There are currently recipes available (including binaries at binstar) for installing fenics on linux using conda (see https://github.com/Juanlu001/fenics-recipes).
On OS X 10.9, however, the building recipes fail (for details of how it fails, see https://github.com/Juanlu001/fenics-recipes/issues/3). It is a problem with libstdc++ explained here: http://stackoverflow.com/questions/13445742/apple-and-shared-ptr.
It would be great if someone with insight on compiler flag for OS X 10.9 could update the building recipes and upload binaries on binstar, so it becomes as easy to install fenics with conda on OS X as it is on linux.
