This does not really seem THAT urgent to me. I mean if it really is
that much of a problem, then simply install the correct client library
to each of the client machines.

IBX is a set of Interbase Components that comes with Delphi. It
expects to find a client library called gds32.dll. It will first look
in the working directory (generally the folder the application is
launched from) and failing that it looks through the path environment
variable until it finds one.

You will not be able to test gds32 for a 1 major 5 minor build number.
This is because the IBX components wont work unless it is 6 major or
better. You best hope is to compare for yourself both client libraries
and see whether there is something that distinguishes them in the
comments etc.
