There was a similar thread a while back about this sort of thing. I don't think it was ever resolved there, though, but you might gleam something useful:

I would be interested in knowing what OS and version you are using, the type of filesystem you're using there, and a clarification that the script you're seeing this error with is a Perl script and not another executable. Seeing your #! line and knowing the location and version of your Perl executable might be interesting also.
