Do the IBObject components work with Firebird embedded?

I followed the IBPhoenix instructions for copying the fbembbed.dll to
the directory where my app is. I tried renaming it to fbclient.dll and
then to gds32.dll, as the readme instructs. When I try to connect my
IBDatabase, I get ISC error, unavailable database. If I start the
Firebird server, my IBDatabase connects, so I know the settings are
correct, at least for that.
