Wow,
on my MacIntel OS X 10.4.11 box the following command *does work
fine*:
find /Users/Shared/sage/sage-4.0.2/devel/sage/sage// \( -name *.py \) -
exec grep -i -H cannot {} +
especially this command has got this "GNUish +" at the end, but on my
MacPPC OS X 10.4.11 box I get this strange error message (find: -exec:
no terminating ";"), too.
Weird!
So it is not a OS X 10.4.11 issue, but rather a MacPPC versus MacIntel
issue --- OS X 10.5 won't install on my MacPPC box (it has got only
550MHz), could someone please check this on a MacPPC with OS X 10.5,
e.g. at the Sage build farm?

This version of the command works fine on *both* the OS X 10.4.11
MacIntel and MacPPC, and is fast.

This one works on both boxes, too, but behaves way slower.
