[linux-lvm] final LVM2 utilities for 2.6 kernel don't seem to work

[Robert P. J. Day]

  after having configured a kernel with device mapper support,
and installed both the libdevmapper and LVM2 tools, when i ran
just the command:

  # pvcreate --version

what i got was:

  /dev/mapper/control: open failed: No such file or directory
  Is device-mapper driver missing from kernel?
  /dev/mapper/control: open failed: No such file or directory
  Is device-mapper driver missing from kernel?
  Incompatible libdevmapper 1.00.02-ioctl (2003-07-12)(compat) and kernel driver 
  LVM version:     2.00.05 (2003-07-18)
  Library version: 1.00.02-ioctl (2003-07-12)

i was working with the 2.6.0-test1-ac2 version of the kernel, which
i'm assuming i didn't need to patch any further since it already
had the config options for device mapper and v4 ioctl.

did i assume incorrectly?  or did i mess up something else?  i
build device mapper support directly into the kernel.
