Oh, yes indeed, it is outdated.

Seems I have to re-write it ;)
Alternatively you can read the PTXdist Guru documentation [1], section 4.2.

Here we go. Use this way instead:

[jbe@host]> /usr/local/lib/ptxdist-2013.12.0/bin/ptxdist newpackage

usage: 'ptxdist newpackage <type>', where type is:

  host                     create package for development host
  target                   create package for embedded target
  cross                    create cross development package
  klibc                    create package for initramfs built against klibc

  src-autoconf-lib         create autotoolized library
  src-autoconf-prog        create autotoolized binary
  src-autoconf-proglib     create autotoolized binary+library
  src-cmake-prog           create cmake binary
  src-qmake-prog           create qmake binary
  src-linux-driver         create a linux kernel driver
  src-make-prog            create a plain makefile binary
  src-stellaris            create stellaris firmware
  font                     create a font package
  file                     create package to install existing files
  kernel                   create package for an extra kernel
  barebox                  create package for an extra barebox
  image-tgz                create package for a tgz image
  image-genimage           create package for a genimage image

[jbe@host]> /usr/local/lib/ptxdist-2013.12.0/bin/ptxdist newpackage src-linux-driver

ptxdist: creating a new 'src-linux-driver' package:

ptxdist: enter package name...........: mydriver
ptxdist: enter version number.........: 1
ptxdist: enter package author.........: Juergen Borleis <jbe@pengutronix.de>
ptxdist: enter package section........: project_specific

generating rules/mydriver.make
generating rules/mydriver.in

local_src/mydriver-1 does not exist, create? [Y/n] Y
./
./@name@.c
./wizard.sh
./Makefile

Then enable this new package in your menuconfig, modify the file in
"local_src/mydriver-1/mydriver.c", build your rootfs with "ptxdist go".

Happy hacking,
Juergen
