NCAR is the (US) National Centre for Atmospheric Research, NCARG is a graphics library, maps database and applications for the same, and NCAR Command Language (NCL) is interpreted language for the above. Installing the software from source is not recommended: "We highly recommend that you use a precompiled NCL binary rather than attempting a build from source code....

The GNU Compiler Collection (usually shortened to GCC) is a compiler system for C (gcc), C++ (g++), Java (gcj), Ada (GNAT), Objective-C (gobjc), Objective-C++ (gobjc++), and Fortran (gfortran). Circumstances will arise when you will want to use a particular version of GCC rather than the system version.
Set the environment variables manually for GMP, MPFR and MPC. Or use modules.
module load gmp/4.3.1
module load mpfr
module load mpc

LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is used to model atoms or as a parallel particle simulator at the atomic, meso, or continuum scale. It has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems. You may remember a difficult install from the past.

MVAPICH and MVAPICH2 is an implementation of MPI for computing systems and servers using InfiniBand, 10GigE/iWARP and RoCE & etc networking technologies.
Installation consists of downloading the tarball into an appropriate directory, extracting it, loading the enviroment variable modules, using of some previously established configuration files, runnig make and make install, and establishing the symbolic links. Note that MVAPICH and MVAPICH2 are entirely different products.

Tuning and Analysis Utilities (TAU) is a program and performance analysis tool for high-performance parallel and distributed computing with a suite of tools for static and dynamic analysis of programs written in C, C++, FORTRAN 77/90, Python, High Performance FORTRAN, and Java.
You'll also need the Program Database Toolkit (PDT), also available from the same location. Let's install that first. You'll need to set your environment variables. You use modules, right?
module load gcc/4.4.4
modulel load openmpi-gcc/1.3.4

Let the home page describe what it is about (in the worst possible English): "MrBayes is a program for the Bayesian estimation of phylogeny. Bayesian inference of phylogeny is based upon a quantity called the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. The conditioning is accomplished using Bayes's theorem.
