You need to reverse the order in which libraries are given--I guess my
description was a bit confusing, sorry.  Could you please try again
with

g++ -Wall vtktest.c -o vtktest -static -lvtkIO -lvtkFiltering
-lvtkCommon -lvtkDICOMParser -lvtkpng -lvtkzlib -lvtkjpeg -lvtktiff
-lvtkexpat -lvtkMPEG2Encode -lvtksys -lpthread -ldl -lm

I still think that you should use "g++".  It might be enough to add
-lstdc++, but I am not if that is the only difference.  Note also that
although some of those libraries from the vtkIO dependency chain might
not be required for linking after all, you should not bother with
that, as they will not enlarge the resulting executable.

If that still does not help, try using CMake for configuring the
project and generate a Makefile. Then a "make VERBOSE=1" will give you
a chance to see what commands CMake figured out for building your
project.  Here is a sample CMakeLists.txt that might just do the
trick:

----BEGIN----
PROJECT (vtktest)

FIND_PACKAGE(VTK REQUIRED)
INCLUDE(${VTK_USE_FILE})

ADD_EXECUTABLE(vtktest vtktest.c)
TARGET_LINK_LIBRARIES(vtktest vtkIO)
----END----
