I'm trying to use pypackager to build a deb for squeak. I want to install some files to /media/mmc2, however, when I run the installer it baulks with the message:

error setting ownership of 'media/mmc2/squeak': Operation not permitted.

I suppose this is due to the FAT32 file system. Is there any way around this without installing the file to say /var/tmp and then moving it with a post processing script.
