These are symptoms of bugs in nc-config and nf-config, not calling each other 
to determine what features are supported.  We need to get out a bug-fix release
for netcdf-fortran soon, because I think these bugs are fixed in the current 
snapshot.
Unfortunately, there's no bundled snapshot release of netcdf-fortran yet, only
an svn source tree. The issue for tracking is here:

  https://www.unidata.ucar.edu/jira/browse/NCF-165

I believe running "make check" for the Fortran release should verify that you 
actually
have support for version 2 interfaces and for the netCDF-4 APIs.  Let me know 
if your
"make check" for Fortran does not include these lines:

  *** Testing netCDF v2 api for F77.
  *** SUCCESS!
PASS: tst_f77_v2
 
 *** Testing definition of netCDF-4 vars from Fortran 77.
 *** SUCCESS!
PASS: ftst_vars
 
 *** Testing netCDF-4 vars from F77 with new types.
 *** SUCCESS!
PASS: ftst_vars2
 
 *** Testing enum and opaque types.
 *** SUCCESS!
PASS: ftst_vars3
 
 *** Testing VLEN types.
 *** SUCCESS!
PASS: ftst_vars4
 
 *** Testing compound types.
 *** SUCCESS!
PASS: ftst_vars5

If you see all those, then that verifies "nf-config --all" is wrong
about the supported features.  Also, DAP access is supported in the
Fortran APIs as a consequence of support in the separate C library,
but I see it's not explicitly tested for when "make check" is run.

The current versions of nc-config.in for the C release and nf-config.in
for the Fortran release are available here:

  http://svn.unidata.ucar.edu/repos/netcdf/trunk/nc-config.in
  http://svn.unidata.ucar.edu/repos/netcdf-fortran/trunk/nf-config.in

Unfortunately to fix nc-config and nf-config requires starting over by 
copying the two files above into the top source directory of the respective 
releases, rerunning configure, make check, make install for the C release,
then rerunning configure, make check, make install for the Fortran release.

Please let us know if that doesn't fix the problems with nf-config returning 
the wrong information, and thanks for reporting the bugs!
