ok, you're running 2.9.14 which is not the current release. I don't have a copy 
of the 2.9.14 manual, but since surfc was added to Octave's sources in November 
2007 and we are currently at 3.0.1, it is likely that surfc is not present in 
2.9.14.

Please download the most recent sources and compile/install those.
