myDSL Extensions (deprecated) :: .dsl creation

I've created a .dsl with deb2dsl script.
I wanted to add an icon so I modified the .dsl adding the dir
home/dsl/.xtdesktop with the icon and the lnk.
When I try to load the dsl I get this error:
touch: /tmp/restart_xtdesk: Permission denied

Did you happen to attempt installing a myDSL extension as root before doing this?
"touch /tmp/restart_xtdesk" is a command issued from mydsl-load. If the temp file is created as root first you're not going to be able to create/modify it as dsl.

Try "sudo chown 1001.50 /tmp/restart_xtdesk" or "sudo rm /tmp/restart_xtdesk" and see if it works after that.
