"Script file creation failed. The created file is corrupted."

Attempting to test a short Perl script in SAM 6.0, getting "Script file creation failed. The created file is corrupted."

What does this mean? How do I troubleshoot this?

The script runs fine on the target by itself. The target is OSX Server 10.6.8. A very simple script runs fine from SAM as well; once I attempt to port a script that's already working stand-alone, getting the above error message. Trying googling for it, nothing comes up.

When I watch a /tmp folder on the target, I do see a temp file being created, then disappearing quickly.

Thanks!
