Please see http://ask.sagemath.org/question/3110/osx-108-installation-failure
"Using the binaries. Tried both 10.6 and 10.8 osx app versions. System running 10.8.5. Sage does not appear to load. The following appears at the end of the log: File "/Applications/Sage-5.12-OSX-64bit-10.6.app/Contents/Resources/sage/local/lib/python/sre_constants.py", line 18, in <module> from _sre import MAXREPEAT ImportError: cannot import name MAXREPEAT" A quick search seems to say that this an incompatibility between Python used to compile something and system Python. That shouldn't affect us, but apparently it did... thought it was worth bringing up to a a wider forum in case there is an easier fix than compiling on the user's system from scratch. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
