The good new first:
The program runs fine on my system (XP, AS Perl 5.8.6)

I'm puzzled about the "isn't numeric" warning: As I understand it, it's not supposed to be numeric because it'a a path
No. The return value of GetFolderPath is a path. The CSIDL_LOCAL_APPDATA is a numeric constant that tells the function which path to return.

Note that code in the style of 
if ($something) 
{
  use Some::Module;
}

does not DWYM. use is a compile time statement. There are some nodes about conditionally loading modules at runtime here. Go Super Search.

Also you show poor style in your use of the ternary operator. Better write that as 
print defined $realhome ? "realhome:  $realhome\n" : "\$realhome not d
+efined\n";
