We could better qualify that "precompiled" is the ZeroC download only.  Maybe remove precompiled and reword to include "ZeroC binary download" or similar.  The Ice version provided by Linux distributions will be compiled against the default python version they provide which at the moment is python 2.7.  Given that the distribution versions are patched to fix various bugs and work with the default python, this should be recommended over installing ZeroC's version where this is possible since it will integrate with the rest of the system and works with a security supported version of python (2.6 is obsolete).  Likewise homebrew ice is built against the system or homebrew python version.  The only platform which requires the ZeroC download is Windows.
