Re: version of netcdf4 libs in ncl 5.1.1

Hi Mary,

The file I'm trying to read was created with netcdf 4.1.1. It appears
the problem is that ncl 5.1.1 is built with an earlier version.
(I also tried IDL, which used an earlier version of netcdf and it
also failed) I downloaded the new ncl 5.2 and I'm able to read the
file both on intel mac and x86_64! So I'm assuming that uses netcdf
4.1.1? I'm staging the file to our FTP server if you want to have a
look. It's about 500MB, though. I'll let you know when it's ready...

Here's the error message:
