using 2.1 on fc8,

I have migrated my code from a machine with fb1.5 installed, when I go to
compile with fb2.1, using the same compile instructions, I get the issue
below. Changing fbclient to fbembed makes it work but, AFAIK, such a change
should not be necessary.

-g -lfbclient -lrt object/dbtrig.o object/daemonise.o object/db_error.o
