While working with pkgsend to test out my changes for bug 1324, I forgot to
create a file I was adding to a test package. This is the resulting traceback:

pkgsend add file /tmp/libc.so.1 mode=0555 owner=root group=bin
path=/lib/libc.so.1
Traceback (most recent call last):
  File "/export/home/swalker/devel/pkg-1324/proto/root_i386/usr/bin/pkgsend",

    ret = main_func()

    trans_add(pcfg, pargs)

    status, msg, body = t.add(config, trans_id, action)

    datastream = action.data()
  File "/export/home/swalker/devel/pkg-1324/proto/root_i386/usr/bin/pkgsend",
line 167, in opener
    return open(args[1], "rb")
IOError: [Errno 2] No such file or directory: '/tmp/libc.so.1'

=========

It really should fail with a friendlier message.
