!!! Could not extract the saved environment file. This is usually

!!!     /var/db/pkg/dev-perl/Compress-Zlib-2.001/environment.bz2
!!! Try copying this file, bunzip2ing it and sourcing it using a new
!!! bash shell (do not continue to use said shell afterwards). You
!!! should get an error that give you a rough idea of where the
!!! problem lies.
