Solaris/pkgsrc-current: no system rules (sys.mk)

["Mehul N. Sanghvi" <mehul.sanghvi%gmail.com@localhost>]

It has been probably about 6 months or so since I did anything with pkgsrc, so
I did a 'cvs update -PAd' and then a 'pkg_chk -u -q' to see what needed
updating.  Since bootstrap-mk-files needed an update, I decided to work with
that first.  What does it mean when it says "no system rules (sys.mk)" ?  And
how can I fix it ?
