The above errors are to be expected, and do not indicate any problem
with the netCDF installation.  You are done installing netcdf if the
library, utilities, and documentation (in the lib/ and bin/ and man/
directories) are where you want them.

The errors in "config.log" are just a result of the configure script's
normal operation.  As it says in the INSTALL document

    The configure script will also create the file "config.log", which
    will contain error messages from the utilities that the configure
    script uses in examining the attributes of your system.  Because
    such an examination can result in errors, it is *expected* that
    "config.log" will contain error messages.  Therefore, such messages
    do not necessarily indicate a problem (a better indicator would be
    failure of the subsequent "make"). ...
