[netCDF #TJN-278511]: Check Fail -- Building NetCDF Fortran Libs in Minimal Ubuntu Container

Hi Colin,

Thanks for your patience.  Do you have the `config.log` file generated when you 
ran `configure`? There should be a compiler specified between `../libtool` and 
`--tag=F77`.  Typically this indicates that either the `F77` or `FC` 
environmental variables needs to be defined to specify the compiler you are 
using.  For example, if you're using `gfortran`, you'd want to run configure as 
follows:

    $ FC=gfortran ./configure [configure options for netCDF-Fortran you 
typically use]

If this doesn't fix the issue, let me know; if you provide the `config.log` I 
should be able to try to replicate and fix the issue.  

Thanks! Have a great day,

-Ward
