#54351: biber of biblatex-biber fails

 Priority:  Normal          |  Milestone:
Component:  ports           |    Version:  2.4.1
 Keywords:  biber biblatex  |       Port:  biblatex-biber
----------------------------+----------------------------
 I recently did a selfupdate and after the update the biber command of
 biblatex-biber package no longer works.  It worked fine for years before
 this.  I have the current macports version:
  biblatex-biber @2.5_2+perl5_24 (active)
 (There is a newer version of biber at sourceforge but macports is behind
 it seems.)

 And the current biblatex version (from tex.log file) is:
  Package: biblatex 2016/05/14 v3.4

 Here is the error message when running biber:

 {{{

 Any ideas?  Or could someone update biber and biblatex to current versions
 in macports which might just resolve the issue?
