Can't be the -w after the shebang, the system log would not change the case of the character..and it specifically references a "W" not a "w".

This is a long shot..but are you writing this code in a windows environment then moving it to a *unix server? The following line might be your culprit because of the carriage return after the "return"...
return $WebPage->popup_menu ( -values =>
Try it this way:
return $WebPage->popup_menu ( -values =>
There are instances where carriage returns are translated into "." thus the concatonation reference in the warning...I'd like it if you tried taking it out just to humor me...

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
