[MacPerl] Am I missing some crucial step in the installation?

["Julie O. Cross" <jox@ccsalpha2.nrl.navy.mil>]

Dearest List Denizens,

Let me preface this by telling you: (1) this is my second day
reading/working through "The Book" ;-) (MPP&E)* and (2) PowerBook 3400c,
MacOS 8.0, MacPerl 5.2.0r4 from the CD-ROM in MPP&E, and Alpha 7.0 (13 Dec
97).

After diligently working though many examples in MPP&E, it seemed like it
might be nice to look at a "real" script.  Shifting my surf-unit into 2nd
gear, nice and slow, I cruised onto the internet and picked up Joshua
Gemmell's contribution "Mog" (as follows):

   Mog (Joshua Gemmell) is a droplet that will change a
   file's (or a group of files') creator and type.

   http://www.ptf.com/macperl/depts/Code/Tools&Misc./Mog

Good enough.  Now I've tried running this petite script, both from Alpha**
and directly in MacPerl, and I get the error message

      # Undefined subroutine &StandardFile::GetFile called.
      File '<AppleEvent>'; Line 98

due (apparently) to the line:

      if($file = StandardFile::GetFile()) {

Looking in MacPerl Ä:lib:Mac:StandardFile.pl, I discover that GetFile is
not defined (yikes!).  But StandardGetFile is, so I try changing the
offending line of code to:

      if($file = StandardFile::StandardGetFile()) {

Still no luck.  Still the same error message (now with ::StandardGetFile,
of course).  I have my library search paths set to include MacPerl Ä:lib
and MacPerl Ä:lib:Mac in both MacPerl (preferences) and Alpha (current
mode=>search paths).

I suspect I am missing some crucial aspect of the installation and/or
initialization.  Possibly I should have waited until I _finished_ MPP&E,
but patience is not on my menu.

  Thank you in advance for your kind suggestions,

  Julie
