It appears from the above that the environment variables CC, FC, F90,
and CXX were not properly set to the absolute pathnames of the C,
Fortran-77, Fortran-90, and C++ compilers, respectively, before the
configure script was executed.  My advice is to start over:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 through 5 described near the end of the file
        INSTALL.html.

    3.  Ensure that environment variables are appropriately set.  The
        file "INSTALL.html" contains an example for building
        the netCDF package on a Linux system using the pgf90 Fortran
        compiler.  Use something like

            export CC=/usr/bin/gcc
            export CPPFLAGS='-DNDEBUG -DpgiFortran'
            export CFLAGS=-O
            export FC=/opt/pgi/linux86/bin/pgf90
            export FFLAGS='-O -w'
            export CXX=/usr/bin/g++

        or

            setenv CC /usr/bin/gcc
            setenv CPPFLAGS '-DNDEBUG -DpgiFortran'
            setenv CFLAGS -O
            setenv FC /opt/pgi/linux86/bin/pgf90
            setenv FFLAGS '-O -w'
            setenv CXX /usr/bin/g++

        depending on your user-shell.

    5.  Perform steps 6 through 9 described near the end of the file
        INSTALL.html.
