I'm having a problem with ESMF_regrid which seems to be that the unix
command ESMF_RegridWeightGen is not found. To make the problem easy to
illustrate, I adapted Example 1 from the ESMF_regrid() documentation,
and used the file from the NCEP/NCAR reanalysis. I
uploaded the .nc file to the CGD ftp site given on the webpage.

Here is the example script....

Fri Dec 27 12:33:25 sif scripts> more ex1.ncl
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/esmf/ESMF_regridding.ncl"

         infile =

     sfile = addfile(infile,"r")
     temp = sfile->air(0,0,:,:)

     Opt = True

     Opt@SrcFileName = ""
     Opt@DstFileName = ""
     Opt@WgtFileName = ""
     Opt@ForceOverwrite = True

     Opt@SrcMask2D = where(.not.ismissing(temp),1,0)

     Opt@DstGridType = "5x5"
     Opt@DstLLCorner = (/ -60.d, 0.d/)
     Opt@DstURCorner = (/ 60.d, 355.d/)

     temp_regrid = ESMF_regrid(temp,Opt)

And here's what happens when I try to run it...

I'm running NCL on Mac OSX 10.6.8.

Any ideas on what could be causing this problem?
