    Matt reworked tetgen to use the PETSc include files thus ctetgen cannot be built before the PETSc configure files are generated and written. Hence it is compiling ctetgen using the package.postProcess() method instead of the usual method used for building other packages. The postProcess() is less mature and doesn't yet have checks to prevent unnecessary recompiles etc. Someday it may be improved.
