Namespace clash: HDF v4.2r1 and libnc-dap-3.6.0

[Rick Grubin <grubin@xxxxxxxx>]

System: Mac Powerbook OS X 10.4.6
               GNU compilers (gcc 4.2.0 , g77 3.4.3 or gfortran 4.2.0)

I have a software tool (NCL  http://www.ncl.ucar.edu) that links  
against HDF v4.2r1 and OPeNDAP's libnc-dap-3.6.0 so as to include  
functionality present in those libraries.

After recently upgrading my OPeNDAP components (curl, libxml, libnc- 
dap and libdap) to the most recent versions, I'm unable to link  
against the HDF and libnc-dap libraries because of a namespace clash:

/usr/bin/ld: multiple definitions of symbol _cdf_routine_name
/.../lib/libnc-dap.dylib(single module) definition of _cdf_routine_name
/.../lib/libmfhdf.a(globdef.o) definition of _cdf_routine_name in  
section (__DATA,__data)

This seems odd, as that symbol has been present in both libraries for  
some time now.  I've not seen this behavior on other systems (Linux  
(FC/SuSE), AIX 5).  Suggestions appreciated.

-Rick.
