Found GP/PARI build directory in /home/lami20j/modules_cpan/pari-2.3.0
     (integer-formatted version 2003000).

  ### Math::Pari support of GP/PARI library version 2.3.* should be
  ###   considered cursory only.  One may need to downgrade to 2.1.7,
  ###   or run Makefile.PL with option machine=none if the tests fail.

  ### For example, the test t/55_intnum.t takes a very long time to complete,
  ###   and plotting functions are not supported.
