None of the 3 libraries have anything to do with MPICH - they are the LAPACK 
library, the gnu fortran support library and the BLAS library respectively.

They are all present on the compute nodes - they are not present on itrda and 
probably the other head nodes as well. As you are not supposed to compile on 
the head nodes that should not be a problem but it appears that is exactly 
what you were trying to do. 

FYI if your performance depends on BLAS/LAPACK, using Intel MKL (out of
/usr/local/pkg/mkl/mkl-8.1.014/lib/32/) and link with 
-Bstatic -L/usr/local/pkg/mkl/mkl-8.1.014/lib/32 -lmkl_lapack -lmkl_ia32
