The easiest way is to ask the Finder:

#!/usr/local/bin/perl

$file = "Macintosh HD:SimpleText";
$tsize = MacPerl::DoAppleScript(<<ENDIT);
tell application "Finder"
        size of alias "$file"
end tell
ENDIT
$size = -s $file;
print "$tsize, $size\n";

which returned

58768, 0

Of course, since it used AppleScript, it was slower than molasses.
