I am taking the plunge and starting on my first FireDAC project.

I am taking the plunge and starting on my first FireDAC project.  I am working in XE8, freshly installed on win32.  When I set my connection DriverName to "ODBC", the FireDAC.Phys.ODBC, and FireDAC.Phys.ODBCDef units get included and I can no longer build my project, and it no longer compiles due to the following error:

[dcc32 Fatal Error] data.pas(18): F2613 Unit 'FireDAC.Phys.TDataMeta' not found.
  data.pas(18): Unit 'FireDAC.Phys.TDataMeta' is used by 'FireDAC.Phys.ODBC'

Bug?
