Yep, I downloaded and installed 4.6 (you can create a one-off ubuntu package of it by using checkinstall) in its stead. The -exe option is working now.

Thanks,

The -exe option came out in Gambit v4.5.0 (released August 2009).  The version you are using, Gambit v4.2.8, came out in May 2008.  You need to upgrade!
