[gradsusr] Wgrib2 / g2ctl / gribmap

Mon Jan 23 09:41:19 EST 2012

Thanks to Wesley & Jeff for their suggestions on resolving my problem.

It turned out though that the fix was to 'make' the file from source on my
server. For some reason that resolved the issues.

I had been using an RPM version and tried a precompiled binary, both of
which had problems. Using Cola's gribmap didn't help me, nor did setting
the path in g2ctl.
After 'making' the wgrib2 file, I simply copied it over to the /usr/bin
directory and all is well.

Thanks so much for everyone's guidance. Sometimes even talking problems
through can help to consider another possibility.
