"help legendre_sphPlm_array" produces what I assume was intended:

 -- Loadable Function: Y = legendre_sphPlm_array (LMAX, M, X)

     This function computes an array of normalized associated Legendre

     functions sqrt((2l+1)/(4*pi)) * sqrt((l-m)!/(l+m)!) Plm (x) for m

     >= 0, l = |m|, ..., lmax, |x| <= 1.0


     This function is from the GNU Scientific Library, see

     `http://www.gnu.org/software/gsl/' for documentation.

The problem must then be related to the GSL 2 function, legendre_array.

Ok, I get it now.

Depending on the GSL_MAJOR_VERSION flag, you have a DEFUN_DLD that defines either "legendre_sphPlm_array" or "legendre_array".  In both cases, the oct-file is named "legendre_sphPlm_array.oct".

Now that the problem has been located, a few thoughts:

* I think both functions must be provided if possible (legendre_sphPlm_array is deprecated, but still available).

* This issue will be more elegantly dealt with while integrating your patch named "Add in a bunch of array functions".  I see that you have introduced templates for _array functions, why not deal with legendre_sphPlm_array / legendre_array in a similar way ?
