Looks like some dependecies are incomplete. triMC3D home page at says:

"triMC3D depends on several libraries in order to be built:

   libhdf5 and libhdf5_hl
   an MPI implementation, like mpich2, in order to compile the parallel  

Furthermore, python 2.x and packages pytables, scipy, VTK and  
numarray/numpy are extensively used for model preparation and  
post-processing of simulation data."

Did you install all of them?

triMC3D doesn't appear to be widely used, so better ask the author for  
further advice.
