Yes.

}When I do I get the following error:

}# # Can't locate auto/Image/Size/gifsize.al in @INC.
}File 'Macintosh HD:perl:MacPerl Ä:lib:AutoLoader.pm'; Line 26

Because you didn't Autosplit the file.

Here's a piece of mail I sent to the list in response to an earlier message
a few months ago:

}You don't get around the Makefile script.  They do expect that Perl modules
}will only be installed on Unix systems.
}
}Here are some things to look for when downloading a module from CPAN.  If
}there are any files ending in .xs, forget it, since you'll need a C
}compiler to install it.  As far as I know, only Matthias can properly make
}shared libraries.  If all there are is one or more .pm files, put them into
}the appropriate place by hand.  In this case (having just downloaded
}Image-Size from CPAN), there's only a Size.pm, so put that in a folder
}named Image somewhere in your MacPerl search path.  (You should probably
}maintain at least one folder in your MacPerl search path outside of your
}MacPerl folder, so you don't need to rescue modules you've added when a new
}MacPerl comes out.)  Make sure it's a Macintosh text file, and not a Unix
}text file, or MacPerl will choke.
}
}Now you try it (I'm using the all.t in the t directory) and you find that
}it complains about a module that it wants to Autoload that's not being
}found.  On a Unix system, during the make process the file would be
}Autosplit, and each individual routine below the __END__ would go in an
}:auto:Image:Size:name.al file, with name replaced by the routine name (so
}you would have gifsize.al, etc.)  But often you don't need to do that.  The
}first thing to try is to find the __END__ line in Size.pm and simply
}comment it out.  And, behold, all but one of the tests (that for the
}included ppm file) work.  Mission almost accomplished.  I'll leave it to
}you to start up the debugger and figure out why the ppm isn't working if
}you want, but if you don't care about ppm, you're set.
}
}The steps again: put Size.pm in a folder named Image in your MacPerl search
}path.  Change it to Mac text, and edit it to comment out the __END__. Have
}fun!

}I'm afraid I have no idea to what auto/Image/Size/gifsize.al refers.

}Any help would be appreciated.

The procedure outlined above works.  I even figured out what was wrong with
the ppm (another \n != \012 problem).  If this is good enough, then you're
set.  If not, I went ahead and Autosplit the file by hand and I can make it
available when I get the time to package it into a sit.hqx.  Let me know.
