If one set the cpt via -N

grdcontour lixo.grd -Nlixo.cpt -P -JX10 > lixo.ps
grdview [ERROR]: Syntax error: Must specify color palette table
unknown [ERROR]: Failed to call grdview

and from external interfaces neither -C or -N work

julia> grdcontour(G, color=cpt, show=1, N=true,  Vd=1)
        grdcontour  -JX12c/0 -C -N -P -K > C:\tmp\GMTjl_tmp.ps
GMT [ERROR]: CPT api_colors2cpt_16176.cpt has no z-slices!

apparently because in this case at the call

if ((P = GMT_Read_Data (API, GMT_IS_PALETTE, GMT_IS_FILE, GMT_IS_NONE, GMT_READ_NORMAL, NULL, cptfile, NULL)) == NULL) {

cptfile is an empty string.

Closed this too soon. The fix fixes the command line side but external calls still fail due to the reason exposed.
