I think that it is here "-L-lfl" this is assuming that libfl.a is from flex. 
My suggestion is to replace the d stuff with a c hello world and get that 
running. Then get the D version working. I would also recommend that you 
compile and link the D code in 2 steps. To do that run gcc as you would for 
a normal link but also link with libphobos (or something similar for tango)
