|If you see the error|
/usr/local/lib/libz.so.1: no version information available (required by python)it has to do with the version of libz installed. The reason for the current version has to do with the version of libz that libxml2 requires. A newer version of both will resolve the issue, but due to many reported issues with this update, we reverted to the older version of libz and libxml2. Note that the warning is not going to hurt anything, so it can be ignored.
We do not recommend using the options below.
If you still wish to update libz and libxml2 to their newer versions to avoid the message, type:
