[Ifeffit] error on installing demeter on MacOSX 10.11.6

[Valerio Scagnoli]

Dear all,
I was trying to install demeter on my Mac with mac port and the installation seemed to run smoothly (after following the advice on the installation page!).
However, when I try to start Athena from the command line I get the following error message:
bash-3.2$ athena
IO::Compress::Base::Common version 2.069 required--this is only version 2.015 at /opt/local/lib/perl5/vendor_perl/5.24/Compress/Zlib.pm line 10, <DATA> line 1.

I tried to install the following zlib packages and uninstall/reinstall demeter, but the error still remains.
bash-3.2$ port installed |grep  zlib
  p5.24-compress-raw-zlib @2.69.0_0 (active)
  zlib @1.2.8_0+universal (active)

I have the following perl package installed
bash-3.2$ port installed |grep  perl
  p5.24-libwww-perl @6.150.0_0+ssl (active)
  p5.24-perl-ostype @1.10.0_0 (active)
  p5.24-perlio-layers @0.11.0_0 (active)
  p5.24-perlio-utf8_strict @0.6.0_0 (active)
  perl5 @5.24.0_0+perl5_24 (active)
  perl5.24 @5.24.0_0+universal (active)

Any help will be appreciated.
