New Revision: 399703
URL: https://svnweb.freebsd.org/changeset/ports/399703

Log:
  When listing dependencies, export the common command execution results.
  
  In some basic benchmarks this sped up 'all-depends-list' about 20%.  x11/kde4
  went from 52 seconds to 41 seconds.  More improvement is expected once
  more command executions are cached in the 'export_ports_env' function.
  
  With hat:	portmgr
