[ncl-install] szip

[Mark Branson]

Well, I'm getting a little further with the full ncl/ncarg install on  
my Mac ppc G5 but still not quite there:

I'm getting this error sprinkled in parts of the make output:

/usr/bin/ld: Undefined symbols:
_SZ_encoder_enabled
_SZ_BufftoBuffCompress
_SZ_BufftoBuffDecompress

which I assume is related to szip.  But I thought you don't need this  
if you don't want netcdf-4 support,
and I answer "no" to that in the configure script as I'm just using  
netcdf v3.6.2.

Or perhaps it's needed for something else???

Thanks!
