For classic server there are two optional backward compatible client libraries.
These are libfbclient.so and libfbembed.so.  

libfbclient.so) enables your client to be multithreaded but must connect to a 
                database via a server.  
libfbembed.so)  allows the client to directly open the database file, but does
                not support multithreaded access

Your current setting is:
EOF
    printStatus

    echo ""

    quitIfRealFile @libdir@/libgds.so
    quitIfRealFile @libdir@/libgds.so.0
