"Input/output error" usually means a physical issue with the hardware
(not a permission error, as some other replies have claimed).  The
output of "dmesg" may have more detailed error messages; in general you
should probably be considering the possibility of disk failure.

(I have _no_ idea why it only happens via #! and not otherwise.  That's
very weird.)
