Hi Dave,

I'm not sure I understand the problem.  The following has not been tested.

How about using the Perl
    BEGIN { ... }
so the code inside { and } would be run as soon as it has been read
by the parser but before the rest of the code compiles?

Or maybe,
    foreach (@possible_directory)
        if (-e "$_/$filename")
            do "$_/$filename";

Please summarize to the list once you've fourd the best solution.
