**************************************************************
You seem to be missing the template directory needed by
configure. If you just copied the source from the Postgres
distribution you should instead have issued the command
'make standalone' which would have built a distribution
containing the necessary template directory. The other
option is that your trying to build from the source
which is meant to be placed in the Postgres distribution
directory 'interfaces/odbc'. Depending on your case either get the
standalone source from the following Web site:

	www.insightdist.com/psqlodbc/

or issue the 'make standalone' command from the
'interfaces/odbc' directory of your Postgres Distribution,
or copy the distribution file you have to your Postgres
distribution's 'interfaces/odbc' directory and try
again.

If neither of these is the case than please complain
kindly to the maintainers, their e-mail addresses can
be found in the Readme files.
