Hi,

I have been building 64 bit binaries of Sage on a MacIntel OSX 10.5
for a while, but getting things to build from scratch is still rather
complicated and there are a bunch of issues - see 
http://wiki.sagemath.org/osx64/sage-3.2.3

But I have made available a binary in

   http://sage.math.washington.edu/home/mabshoff/osx-64bit-binaries/

Note that the dmg does not contain a fix for Ctypes, so to get the
notebook to work copy _ctypes.so also available in the above directory
to

   $SAGE_ROOT/local/lib/python2.5//site-packages/

Note that at exit right now we get a bunch of nasty messages like

sage.bin(9066) malloc: *** error for object 0x1065a8030: Non-aligned
pointer being freed (2)
*** set a breakpoint in malloc_error_break to debug
sage.bin(9066) malloc: *** error for object 0x1065a8038: Non-aligned
pointer being freed
*** set a breakpoint in malloc_error_break to debug
sage.bin(9066) malloc: *** error for object 0x1065a7048: Non-aligned
pointer being freed
*** set a breakpoint in malloc_error_break to debug
sage.bin(9066) malloc: *** error for object 0x1065a7030: Non-aligned
pointer being freed (2)
*** set a breakpoint in malloc_error_break to debug

This is caused by the Rational() destructor in libSingular and I can
quiet it easily by introducing a leak, but I have not looked into
fixing this properly yet. Maybe SD 12 material :)

Anyway, please give it a spin and report back issues. It should be
noted that this build is not ready for prime time!

Cheers,

Michael
