Perfect, thank you!

I installed only r-base-core and r-base-dev (gfortran, blas and lapack
were needed for compilation).

... much downloading and compiling ...

Error in (function (start, objective, gradient = NULL, hessian = NULL,  :
  gradient function must return a numeric vector of length 6
In addition: Warning messages:

  NA/NaN function evaluation

Upstream says those warnings can be ignored.  I also tried the above
with r-recommended installed as well and got the same result.

As a DD, you already have access to all our porterboxes[1]!  :-)
