Howdy Steve!

gfortran works just fine with netCDF. In fact, it is what I use every night for 
automatic testing. And if the tests from "make check" succeeded, then we know 
it works on your machine as well.

Where are the .mod files? They should be in /usr/local/include if you did not 
provide a --prefix argument when you ran the netCDF configure script.

With gfortran, I believe that one uses the -I option, as I see from the 
documentation (below). You need to pass this argument, with the location of 
your mod files:


4.5 Options for Directory Search
================================

There options affect how affect how `gfortran' searches for files
specified via the `INCLUDE' directive, and where it searches for
previously compiled modules.

   It also affects the search paths used by `cpp' when used to
preprocess Fortran source.

`-IDIR'
     These affect interpretation of the `INCLUDE' directive (as well as
     of the `#include' directive of the `cpp' preprocessor).

     Also note that the general behavior of `-I' and `INCLUDE' is
     pretty much the same as of `-I' with `#include' in the `cpp'
     preprocessor, with regard to looking for `header.gcc' files and
     other such things.

     This path is also used to search for `.mod' files when previously
     compiled modules are required by a `USE' statement.

Let me know if this helps.

Thanks!

Ed
