Best. Or simply use the static ones and -XLA.
If you use the static units, a simple -XLAfbclient=fpbclient.2 might
solve this too.

This is a bit of a slippery slope. This kind of autodetections always have a
certain percentage of failures and dubious cases. (what if multiple versions
are in the path? what if .3 comes out? The FPC release could become
In such case, the main program should be able to initialize the library, and
left to the application builder, which can then adapt in case of problems
without needing a new toolchain.
Today it is fbclient, and tomorrow we have detection code with multiple
cases names, paths etc for every library on an Unix system.
