[Baptiste Daroussin]

Author: bapt
Date: Sun Feb  8 15:00:57 2015
New Revision: 378660
URL: https://svnweb.freebsd.org/changeset/ports/378660
QAT: https://qat.redports.org/buildarchive/r378660/

Log:
  Nuke the realpath from find-lib allowing /usr/local to be a symlink
  
  For now this is a copy/paste from actual-package-depends.sh, probably moved into
  a shared function once the exp-run shows everything is ok
