Does this error still occur if you run the Chimera app after copying it
to your local disk?
We never intended for Chimera to be run from the disk image because
Python creates compiled modules in the same directory as the source
Python modules. Also, Apple has been tightening security around
downloaded applications, so that also might contribute. Notice that
your error is "Operation not permitted", not "Permission denied", which
is the more standard error (errno is 1 instead of 13) when file/folder
permissions are involved.
