This is expected.  The C compiler must be told what Fortran-calling-C
conventions to use.  This is done by defining a C macro in the
environment variable CPPFLAGS before executing the "configure" script.
For the Portland Group Fortran compiler, this macro is "pgiFortran".
The installation instructions in the file "INSTALL.html" or on the
webpage

    http://my.unidata.ucar.edu/content/software/netcdf/INSTALL.html

contain examples of this.

That's another way.  That netCDF distribution won't build on a different
system, however, which is why the examples show the use of the CPPFLAGS
envronment variable.
