[FieldTrip] invalid MEX file error in clusterstat

I'm running ft_sourcestatistics with the following cfg:

%%% cluster statistics
cfg = [];
cfg.parameter           = 'stat';
cfg.method              = 'montecarlo';
cfg.statistic           = 'depsamplesT';
cfg.clusteralpha        = 0.05;
cfg.numrandomization    = 1000;
cfg.correctm            = 'cluster';
cfg.design(1,1:2*Nsub)  = [ones(1,Nsub) 2*ones(1,Nsub)];
cfg.design(2,1:2*Nsub)  = [1:Nsub 1:Nsub];
cfg.ivar                = 1;
cfg.uvar                = 2;
cfg.alpha               = 0.025; %one sided alpha!!

stat_clus = ft_sourcestatistics(cfg, Rem{1:Nsub}, Rec{1:Nsub});

and get the below error, am I doing anything wrong (I must admit, I'm 
running a 2 year old script (which has already generated new data out of 
2 year old source data without any errors: very impressive backward 
compatibility!), or is there just a MEX file missing?


??? Invalid MEX-file 
undefined symbol: mxCreateNumericArray_700.
