Subject: Cannot compile "matlab function block" in linux

I have an Simulink model in which I use a matlbab function block. 
The block contains a simple calulation:
function power= fcn(espd,calLoad,maxTorque)
%#codegen
power = espd*calLoad*pi/60*maxTorque/100000*3600;

When I build the code an genereate it I get the following error:
Making simulation target "OBDFuelEstimator_sfun", ...

### Build procedure for model: 'OBDFuelEstimator' aborted due to an error.

When I remove the matlab function block  no error occurs and the compilation works fine.

Does anybody has a solution for thsi problem, I am using R2011b
