[Dune] ParMETIS 4.0.3: idxtype not declared

[Agnese, Marco]

Hello DUNE,
compiling a code I received several errors in the header 

~dune/dune-istl-2.2.1/dune/istl/repartition.hh 

due to the fact that  'idxtype' is not declared.

I linked these libraries in dune:
ParMETIS  4.0.3
METIS 5.1.0
ALBERTA 3.0.0-rc7
ALUGrid 1.52

I saw in the header that if HAVE_PARMETIS the type idxtype is not defined but from the last versions of ParMETIS 'idxtype' was renamed 'idx_t'.
In the bug tracker it appears to has been solved, https://dune-project.org/flyspray/index.php?do=details&task_id=1163, but I still have the problem.
If I don't link ParMETIS in my project but only METIS, it compiles correct.

Thank you,
regards,

Marco Agnese
