It does not appear in the Build-Depends of libmesh and C++ is mandatory
(macro AC_PROG_CXX in configure.in of libmesh)

mpicxx is just a wrapper. It is not a standalone application, it does
need a C++ compiler to work. In the libmesh case, mpicxx exists but
cannot found a g++ compiler (the AC_PROG_CXX is not very explicit in
this case).
