On our OSF1 system with the same environment variable settings, the
error does not occur:

   ...
  Making `all' in directory /tmp_mnt/scratch/russ/builds/dana-opt/src/f90

  /bin/f90 -c -O typeSizes.f90
  /bin/f90 -c -O netcdf.f90
  ar cru ../libsrc/libnetcdf.a netcdf.o typeSizes.o
  ranlib ../libsrc/libnetcdf.a
   ...

The error message "Severe: netcdf_text_variables.f90, line 57: ... "
is from the f90 compiler rather than from the netCDF software, and the
request to "Please report this error ..." is referring to reporting
the compiler bug to the computer vendor.  It's possible that we are
using a later version of the f90 compiler that has a bug fix for this
problem.  The version we have is

  $ /bin/f90 -version
          Compaq Fortran V5.4-1283
          Compaq Fortran Compiler V5.4-1283-46ABA

One way to get around this problem is to specify that you don't want
the Fortran90 interface built, by setting the environment variable
F90='' before running the configure script (and after deleting the
"config.cache" file).  If you are only using netCDF because it's
needed by some other program that is written in C or Fortran77, then
the Fortran90 interface is unnecessary.  Similarly, if you encounter
errors compiling the C++ interface after skipping the f90 interface,
you can also skip the C++ interface by setting the environment
variable CXX='' before running the configure script.

In the future, it would be better to send netCDF questions to
address@hidden rather than to me, because then they will be
forwarded to someone who can handle them even if I am away from my
email.
