Wait, I think we already fixed this in the past. We have
"fpc-abi-3.2.2", which is provided by fp-units-rtl-3.2.2. So the
relation with lazarus is correctly glued together. But I think
fp-units-castle-game-engine is missing that Depends. Do you agree we
should add it there similar as we do in src:lazarus?

So all libraries need a Depends on a binary from src:fpc with an upper
limit (generated during the build). In that way, the Debian
infrastructure knows that a rebuild (or potentially manual action) is
needed. We don't want it to be too tight. When you said "any new version
of FPC" do you mean each patch level too, or on only minor level? How
about Debian new uploads?

I think that we need to re-build CasteEngine in order for that to work.
The error message is somewhat misleading. The compiler does not find a unit with
the right compiler version.
