You're trying to open a file with trailing whitespace in its name :-)

>From the documentation for open():

"After the filehandle is determined, the filename string is 
processed. First, any leading or trailing whitespace is removed from 
the string. Then..."

On p. 194 (Programming Perl) is an example to protect leading and 
trailing whitespace "in order to open a file with arbitrary weird 
characters in it".

  $file =~ s#^(\s)#./$1#;
  open (FOO, "<$file\0");

They say "but we've never actually seen anyone use that in a script". 
So if you use it, you can mail it to booktech@orielly.com :-)
