[CMake] cmake -E tar on Darwin 10.4

[Tim St. Clair]

Folks -

    I'm running cmake 2.8.0 and noticing an interesting anomaly on
Darwin 10.4 when extracting an external project:

cmake -E tar xfz globus-5.0.1.tar.gz
CMake Error: Problem with tar_extract_all(): Operation not permitted
CMake Error: Problem extracting tar: globus-5.0.1.tar.gz

yet,

tar -xzf globus-5.0.1.tar.gz works fine.

are there any known issues that I'm not aware of?
