odd -w effect

[jduncan]

Just had a wierd error that I've been unable to explain.  
We have a script, foo.pl, with #!/usr/local/bin/perl on the top. A 'which
perl' yeilds /usr/local/bin/perl -- all well and good so far.


 % perl foo.pl
   [things work]
 %./foo.pl
 ": no such file or directory
 %

Hmm.  The only thing thats changed is that we've taken the -w out. Okay,
lets put it back:

 % ./foo.pl
   [things work]
 %

Strange.  Does anyone have any suggestions?
