Well, I don't know seaview, so handle my suggestions with care ;-)

The dynamic lib should do as well.

That means that you don't link against the library with these symbols.

Sorry, this line is competely wrong. Behind -L should be only
directories listed, where the compiler should search for libs.

using

LIB_PATH = -L/usr/X11R6/lib -L/usr/local/lib

is probably overkill already. To link against libform, you have to
use -l:

LIBS = -lm -lform -lX11 -lffm

So, you have to change your linking statement:

>	$(CC) -o $@ align.o seaview.o load_seq.o use_mase_files.o \
>comlines.o xfmatpt.o regions.o $(LIB_PATH) $(LIBS)
