Can't compile unit in D2010/Intraweb project

I have a strange error trying to compile a Delphi 2010 Intraweb Project. Both Debug and Release compiles work fine through the Delphi IDE but I get the following when I try a comple through FinalBuilder (6.3.0.1816)

DMReportBuilder14.pas(28) Fatal: F2063 Could not compile used unit 'TeCanvas.pas'

The datamodule is basically a number of ReportBuilder reports, some with Teecharts using Reportbuilders ppChart.

Anyone come across this before or have an idea what I'm doing wrong?

This looks like a library path issue? Make sure delphi isn’t picking up the version of Techart that is included with delphi if you are using the full version.
