Hi,

A random student with OS X 10.6.4 with a 2.4 GHz Intel Core 2 Duo came
into my laptop, and when I tried to install the sage-4.8-64bit-10.6
app binary [1], it fails with "Symbol not found:
_PyUnicodeUCS4_AsUTF8String".   This is I think the same error message
I saw on numerous laptops when I was at the Joint Math Meetings.
I've pasted the message below.     The binary I had made [2] myself on
bsd.math.washington.edu works fine.
