is is possible that you saved the text file in DOS format,
with CR-LF 
endings instead of LF only?

If "od -t x2 hello.py" shows 0a0d sequences, this
is the case. You could 
use dos2unix to convert.

Just guessing, but I sometimes got similar errors in such
cases.

WHICH ENV

LS -L /USR/BIN/ENV
LS -L /USR/BIN/PYTHON

So the symlink from /usr/bin/python to the real binary is
correct and the real 
binary has the right permissions.

If your line starting with "#!/" weren't the first
line in your script, you 
would get a different error message. Same if the
"#" weren't the first 
character in that line.

This leads to the question whether you can start *any*
executable from your 
home directory (assuming you stored your script somewhere
under your home 
directory). If not so, do you mount your /home partition
with the "noexec" 
option?

Post the content of your /etc/fstab.  You should be able to
do that as a 
normal user.

Kinda funny: Writing this while listening to Queen's
"Another One Bites The 
Dust".

Try sending us the output of the "mount" command.
