Pkg.test() fails

[LuzieH]

Hello,

I cannot get Mex to run. In the beginning I had a problem that Mex could not build, but after adding the Mex path to

ENV["MATLABPATH"]="/home/user/.julia/packages/Mex/5WarT/mexjulia"

manually the Pkg.build() ran through. Unfortunately, Pkg.test() throws the following error

Do you have any ideas on how to proceed?
