Otherwise cmake fails to find PVODE:

-- Detecting CXX compile features - done
-- Git revision: Unknown
-- Found MPI_CXX: /usr/lib64/mpich/bin/mpicxx (found suitable exact version "4.0") 
-- Found MPI: TRUE (found suitable exact version "4.0")

CMake Error at /usr/share/cmake/Modules/CMakeFindDependencyMacro.cmake:76 (find_package):
  By not providing "FindPVODE.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "PVODE", but
  CMake did not find one.

  Could not find a package configuration file provided by "PVODE" with any of
  the following names:

    PVODEConfig.cmake
    pvode-config.cmake

  Add the installation prefix of "PVODE" to CMAKE_PREFIX_PATH or set
  "PVODE_DIR" to a directory containing one of the above files.  If "PVODE"
  provides a separate development package or SDK, be sure it has been
  installed.

This is just when BOUT++ is installed, right?

Yes. Otherwise things are working as is.
