I do not know about unixODBC, but since (2) this file i=1BOas not placed in=
to a
directory trusted by ld.so and (2) its file name is not versioned, I suspect
that libnn.so is a plugin or something of this kind.

[ Just for the record: Debian is a highly organized project.  If there had
  been name clashes, the package would never been accpeted in unstable, at
  the first place. ]

I am not sure this will work.  PLplot applications will need to access libnn
and libcsa as real libraries, in a location looked for by ld.so (eventually
specified by the environment variable LD_LIBRARY_PATH).
