twm-lex.o should be built at this point (after twm-gram.o).  Looks like it 
isn't.  Since the linker doesn't complain about its absence, my guess is 
that there's some phantom "twm-lex.o" file there that shouldn't be. 
Delete it and try again.

If that doesn't work, try compiling lex.c by hand:

   gcc -DHAVE_CONFIG_H -I. -I. -I..    -I/usr/X11R7/include \
   -DXVENDORNAME=\"The\ X.Org\ Foundation\" \
   -DXORG_RELEASE=\"Release\ 1.0.1\" -D_BSD_SOURCE \
   -g -O2 -MT twm-lex.o -MD -MP -MF ".deps/twm-lex.Tpo" \
           -c -o twm-lex.o lex.c

If there's no lex.c in the first place you'll have to generate it (really, 
make should be taking care of this):

   flex lex.l
   sed '/^#/ s|lex\.yy\.c|lex.c|' lex.yy.c > lex.c

Once you have a good "twm-lex.o", "make" should finish the job.
