Changing Icon for Standalone Executable

Hi folks. I'm converting my perl program to a Windows executable for 
distribution. Since it uses wxPerl I'm using wxPAR. The command I'm 
using to do the conversion is:

wxPAR --gui -o wxProdOp.exe wxProdOp.pl

This works fine, giving an executable that runs satisfactorily. However, 
the camel icon associated with the program is not the one that I want. 
I'd rather have my own one. I've tried using the capabilities of 
Win32::Exe to change the icon but it doesn't seem to work.

Any ideas would be much appreciated.
