libksba8 built fine for me, as did fftw3 (10.5.2) What OS version are
you on, anyway?
gcc43 in Fink doesn't install a "gcc" executable in the PATH to avoid
colliding with that from Xcode. In any case, gcc from Xcode and that
from gcc43 both appear to understand the -compatibility_version flag.
Since the compiler line is just calling "gcc" let's make sure that it's
doing the right thing. Can you provide the output from "which gcc" and
"gcc --version" ?
