Comment (by dave.allured@…):

 Same bug here, we refreshed our copy yesterday Feb 11. \\
 Version netcdf-fortran @4.2_11. \\
 Mac OS 10.8.5. \\

 Error messages when calling the F90 version of a simple inquiry function.
 It is ironic that the F90 version of the function can not access the F77
 version which is supposed to be in the same library!  FYI, that is how
 this package works, most of the Fortran 90 functions are just wrappers
 around the F77 versions:

 {{{
 dyld: lazy symbol binding failed: Symbol not found: _nf_inq_libvers_
   Referenced from: /opt/local/lib/libnetcdff.5.dylib
   Expected in: flat namespace

 dyld: Symbol not found: _nf_inq_libvers_
   Referenced from: /opt/local/lib/libnetcdff.5.dylib
   Expected in: flat namespace
 }}}

 This looks like an underscore problem!  From the message above, a single
 trailing underscore is wanted.  But the defined symbol has a double
 trailing underscore in the Mac Ports version:

 {{{
 mac56:~/pm25/prog 23> nm /opt/local/lib/libnetcdff.5.dylib | grep -i
 inq_libvers
 00000000000481c2 T ___netcdf_MOD_nf90_inq_libvers
                  U _nc_inq_libvers
                  U _nf_inq_libvers_
 00000000000051ce T _nf_inq_libvers__
 }}}

 When we built the same version from the original Unidata distribution, the
 defined symbol has only one trailing underscore, and the whole package
 works fine:

 {{{
 mac56:~/pm25/prog 28> nm /usr/local/lib/libnetcdff.5.dylib | grep -i
 inq_libvers
 0000000000073db4 T ___netcdf_MOD_nf90_inq_libvers
                  U _nc_inq_libvers
 000000000000711b T _nf_inq_libvers_
 }}}

 Thanks for looking into this.
