I have a basic "hello world" script that runs fine from the shell if I type "# perl test.pl". If I do a "# chmod 777 test.pl" then type "# ./test.pl", I get no output whatsoever. The only thing I get is this clue in /var/log/messages:

I suspect SELinux may be responsible, but really have no experience with it so have no idea.

Thanks.
