My guess is that you are using Windows ;) If you are using Linux then 
there is a problem with your distro's library manager.

I am sure that it is recommended practice by MS to install dependencies 
in an application's folder. Otherwise there is a risk of stealth 
upgrades/downgrades. For that reason, IBX always checks the application 
folder first when looking for the Firebird DLL and only uses the 
registry to locate it and other well known locations, if it can't find 
it there. I would be surprised if Lazarus's SQL objects don't work that 
way as well.
