The matlab binary must be in your $PATH.

Try starting Matlab by hand as an application to verify that Matlab is set up properly and the license is correct. Under Windows, try running "matlab /regserver", the Matlab C API communicates with Matlab via COM, and apparently the COM interface is not automatically registered when Matlab is installed. Under Linux and other types of UNIX, csh must be installed in /bin/csh.

It's clear that some people have had problems with this in the past, but I don't see a clear description of what I should be doing. Any and all advice welcome.
