it looks like you are trying to compile VMD without either Tcl, Tk, FLTK,
OpenGL or python.
i am wondering of what use the resulting executable is going to be. my
guess is that you
didn't read the installation/compilation instructions thoroughly enough and
are have created
a not very useful Makefile.

for the record, i just compiled the current VMD cvs sources on a fedora 17
machine
using gcc v 4.7.x with the following options:
LINUXAMD64 OPENGL FLTK TK ACTC IMD XINERAMA XINPUT LIBTACHYON VRPN TCL
PYTHON PTHREADS NUMPY

there was not a problem.

cheers,
     axel.
