PAR 0.87 & wxgui - driving me nuts

[Ed W]

I have used PAR successfully to package my app in the past.  Just got a 
new PC and loaded on recent perl (5.8.6), and whatever the latest wxperl 
is.  My script runs fine without PAR, but using PAR gives an error:

Z:\perl\CompressMail\test>ExpressMail.exe
Can't locate Tie/Handle.pm in @INC (@INC contains: CODE(0xdcc640) 
C:\DOCUME~1\edward\LOCALS~1\Temp\par-edward\cache-b53bc287bdf8f848e4f8e830715343cc1b1da556/inc/lib 
C:\DOCUME~1\edward\LOCALS~1\Temp\par-edward\cache-b53bc287bdf8f848e4f8e830715343cc1b1da556/inc 
CODE(0xd53208) .) at Wx.pm line 209.
Compilation failed in require at script/wxGui.pl line 9.
BEGIN failed--compilation aborted at script/wxGui.pl line 9.
BEGIN failed--compilation aborted at -e line 835.

I just can't figure it out because the error goes away if I run the exe 
in the same dir as the original script, which suggests that it's related 
to something not being included

However, if I check the par file then it definitely DOESNT have 
Tie::Handle included, and more annoyingly even if I do -M Tie::Handle or 
even put "use Tie::Handle;" at the top of the script it still doesn't 
include Tie::Handle!!  Grrr.  Why is it excluding it even when I try to 
force it??!

Any thoughts.  Probably something totally obvious and operator error...
Thanks
