[vtkusers] What am i doing wrong

[Henry J. Karpf]

Well I am trying to compile a program and I get:
mpicc -O -g -I /usr/include -DLINUX -DVF_MPI -DLAM_BUILDING 
-DEPETRA_ANSI_CPP -DEPETRA_MPI -DDPapi -DDOUBLE -I../../external/inc 
-I../../external/vtk/include -Wno-deprecated -c cell_surface.c
mpiCC  -g -L/usr/local/lf9561/lib -L../../external/lib/linux 
-L../../external/vtk/lib chisel.o hash.o levelset.o surfs.o cells.o 
functions.o zoltan.o view_factors.o btrm.o timer.o chemkindata.o 
chemkin.o io.o transform.o btrm_solver.o update_aztec.o update_direct.o 
vtkOut.o fortran.o myface.o skrat2.o
cell_surface.o    -lzoltan -lzoltan_mem -lzoltan_comm -lmpi -llam

-lvtkzlib -lm -o ../chisel_linux
../../external/vtk/lib/libvtkCommon.a(vtkDynamicLoader.o)(.text+0xe5): 
In function `vtkDynamicLoader::OpenLibrary(char const*)':
: undefined reference to `dlopen'
../../external/vtk/lib/libvtkCommon.a(vtkDynamicLoader.o)(.text+0xfb): 
In function `vtkDynamicLoader::CloseLibrary(void*)':
.....

I link in the files, and yet i get all these erros, the list is actually 
about 10 times as long as above, any advice?
