Thanks to Helen for resolving this.

For info only - Users of C++Builder 6, not Delphi.

The eval installation as it is at the moment (August 2006) will not
work in C++Builder6 as it needs the .cpp source files to build the
packages.
We had to contact Helen to get the required files before we could
properly build the packages.

On the subject of BDE -> Firebird conversion, it looks like blind
substitution of BDE components with IBO components will negate much of
the power of Firebird and will lead to degradation of performance and
code overkill. We are now reconsidering the whole data architecture
rather than just translating as-is.
