tdata.so is the Teradata driver. I don't understand why 2.3.0 wouldn't be able to open it, when 2.2.11 is obviously using it.

I find that the Teradata client ships with DataDirect ODBC with it. I found this document, http://web.datadirect.com/resources/odbc/perl/install-config.html, for configuring the DataDirect, but I get new errors. Still playing...

The DisableGetFunctions didn't seem to have any effect.
