[Serusers] ld -lfl ??? Does anyone know what package -lfl is??

[Eric Haskins]

I was compiling ser.0.9.4 on a new box and Make  spit this at me

tab.o     -lfl -ldl -lresolv -o openser
/usr/bin/ld: cannot find -lfl
collect2: ld returned 1 exit status
make: *** [openser] Error 1

I have searched far and wide for what the -lfl switch is for so I could 
install the package

Thanks,

Eric
