[PySide] Error installing PySide

[Jim Byrnes]

I am trying to install PySide 1.2.2 on Ubuntu 12.04 fully up to date.

I have been following the instructions here: 
http://pyside.readthedocs.org/en/latest/building/linux.html

I get down to step 4 under Building PySide distribution and get this error:

jfb at jims1204:~$ cd PySide-1.2.2
jfb at jims1204:~/PySide-1.2.2$  python2.7 setup.py bdist_wheel 
--qmake=/usr/bin/qmake-qt4
Removing /home/jfb/PySide-1.2.2/pyside_package
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
    or: setup.py --help [cmd1 cmd2 ...]
    or: setup.py --help-commands
    or: setup.py cmd --help

error: invalid command 'bdist_wheel'

If I do pip list I see that wheel was installed.

Can anyone tell me how to get past this error?

Thanks,  Jim
