That one of the reasons why PSARC 2006/550 (see
http://www.opensolaris.org/os/community/arc/caselog/2006/550/) did not
enable all builtins for the first putback, e.g. for the first putback
into Solaris we only enable a subset of builtins which has been
explicitly tested for compatibilty (and in that case "pkg-get" should
work out of the box...) ....

... anyway... there are two ways to work around the problem:
1. Specify the full path to "uname" (POSIX says that builtins must not
be used of a full path to the comment is used), e.g. using "/sbin/uname"
instead of "uname" should do the trick
2. ksh93 has a command called "builtin" to control the behavour of
builtins, e.g. list builtins, load builtins, remove builtin etc.. In
this case a $ builtin -d /bin/uname # should disable the builtin...
