I doubt it.  Our installation of Perl passes the op.stat tests regardless of the
node those tests are run on.  Our nodes are all 3500's and 3550's; some with
disks and some without.

It is more likely that the node under which perl was built has its directories
set up with apollo acl which emulates the Unix environment under which it was
built, bsd4.3 or sys5.3, whatever the case may be.  On the other hand, your
directories, within which you ran op.stat, probably have an acl setup not
matching that in the perl directories.  If perl was built expecting a bsd4.3
directory structure, he will get unexpected results if the directory structure
turns out to be something else.  Directory and file commands such as chmod
will not behave as perl expects.

Convert your directory containing op.stat (via chacl) to emulate the SAME
directory structure as that under which perl was built.  Then run the op.stat
test again.
