package Glib::String is not registered with GPerl

[dune fluffigt net]

Hi!

I have the following problem:
I have a small Gtk2-application which runs fine with perl gtktest.pl  
but whenever I try to pack it together in a .exe I run in to problem.  
The creation of the exe-file is no problem but when I run it (even on  
the same computer as the one with my perl/gtk environment is fully  
installed) I get this error: "package Glib::String is not registered  
with GPerl at script/gtktest.pl line 30"

And line 30 is "my $treemodel = Gtk2::TreeStore->new('Glib::String',  
'Glib::Int');"

This is a win32-environment and the following things are installed
ActivePerl 5.8.8 build 822
Gtk+ Runtime Environment 2.8.20-1
ppms from lostmind.de (Glib: 1.142, Gtk2: 1.141)

After the exe-file is created, I put the exe in a dir with *.dll from  
gtk\bin and still it wont work. I've also tried to create a basic  
par-file which I've filled with files whenever there was complaints of  
files beeing out of @INC.

Any takes on this?

TIA
