Initialization failure on Mac OS (Lion) and Matlab 2012a

What steps will reproduce the problem? Run the initialization What is the expected output? What do you see instead? Matlab crashes gives this error message:

Seems to have the same problem. In my case it failed at glmnet(x,y). So I block out the entired %write glmnetInstalled.m part. For now I'm able to run testPmtk3 to completion.

I appear to have the same problem as well. Mac OS 10.8.2. The dump shows a similar problem.

There is a try-catch statement after line "% /usr/local/lib/libgfortran.2.dylib is missing", but the catch statement fails to catch the error, as the error crashes Matlab.
Solution: we know that glmnet() is failing on Mac, so the catch block should be executed. Replace that try-catch-end block with one line:
installed=false;
And then run initPmtk3 again.
I do not recommend following the solution in comment #2, as the function glmnetInstalled.m will not be created if you comment that block of code completely.
Updating the glmnet-matlab toolbox solved this for me, just replace the pmtksupportCopy/glmnet_matlab directory with the latest version from here: http://www.stanford.edu/~hastie/glmnet_matlab/
This would also require changing the call to glmnetPredict in cvglmnetMulticlass.m line 55 to: predmat = glmnetPredict(glmnet_object, x, options.lambda, type); and in line 61 to: predmat(which,:) = glmnetPredict(cvfit,x(which,:),options.lambda, type); As the order of parameters for this function has changed.
