problem with perl's `PAR' module

[Werner LEMBERG]

Folks,


I've installed perl's `PAR` module, needed for TeXLive's (self-compiled)
`biber` binary, with

  sudo cpan-5.26 install PAR

on my up-to-date Lion box (using MacPorts from git).  However,
executing `biber --help` fails with

  Perl lib version (5.26.3) doesn't match executable
    'perl' version (5.26.1) at
    /opt/local/lib/perl5/5.26/darwin-thread-multi-2level/Config.pm line 62.
  Compilation failed in require at /opt/local/lib/perl5/site_perl/5.26/PAR.pm line 7.

Indeed, port shows

  port info perl5.26
  -> perl5.26 @5.26.3_2 (lang)

  port info perl5
  -> perl5 @5.26.1 (lang)

It seems that other Perl modules are not sensitive to different lib
and binary versions...  How can I fix that?
