Actually, the error message from print do( 'fred' ); confuses me completly.
What error message? You are aware of the different variants of do? From perldoc -f do 
do BLOCK
  [...]

do SUBROUTINE(LIST)
  [...]

do EXPR
  Uses the value of EXPR as a filename and executes
  the contents of the file as a Perl script.

so probably the file named 'fred' doesn't exist and do returns simply undef - at least that's what it does here (on perl 5.6.0) generating thus a warning about Use of uninitialized value in print ...
