Hi all,
I've noticed a mistake in the Linux launcher script, "start.sh"

it tries to run, "source support/gog_com.shlib", this does not exist (although it usually does for gog packages).
Changing this line to "source gog_com.shlib" makes the game launch fine.

The other slight concern I have is that on every launch, it sets "Nantucket.x86_64" to executable..
This should probably be done by the installer and there should not be a requirement to do this every time the game is run..

Anyhoo - hope this helps if anyone is stuck.
