Wouldn't you also need a separate petsc_complex build, and scripts
(like the "module load petsc/some_version" we use in CFDlab) to switch
around the environment variables PETSc uses?

It's not a good solution, but I don't think it'll change any time
soon.  We could build libMesh with simultaneous Real/Complex support
just by adding another template argument to everything which isn't
already templated around datatype... but PETSc is C and Fortran, and
making that simultaneously compile with multiple datatypes would be
pretty tedious.
