The above message contained the following:

> Our installation of netcdf on PC/linux with Fortran 90 compiler pgf90
> has failed. (However, it does work when using the pgf77 compiler, and
> skipping the f90 part). As we plan to use the numerical model written

Version 5.1 of the pgf90 compiler appears to have a bug in it that
results in this failure.  We are in the process of reporting this bug to
Portland Group.

In the meantime, your options are

    1.  Don't build the Fortran-90 interface.  Go to the top-level
        source directory and perform steps 3 through 9 described at

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

        During step 5, set the environment variable F90 to the empty string.

    2.  Wait until Portland Group solves the problem with pgf90.

    3.  Use a different Fortran-90 compiler -- including earlier versions
        of pgf90.
