Can't get it working in Ubuntu 11.04 fresh install.

I had the tablet working under linux mint (ubuntu 10.10). Now i installed Ubuntu 11.04 formating root, but keeping my home.

I need to install the driver again, and i'm trying to do it with this tutorial:

https://help.ubuntu.com/community/TabletSetupWizardpen

If i add the ppa, when i try to install it, it says
E: Unable to locate package xserver-xorg-input-wizardpen

(code)
alanlock@alanlock-desktop:~$ sudo apt-get install xserver-xorg-input-wizardpen
[sudo] password for alanlock:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package xserver-xorg-input-wizardpen
alanlock@alanlock-desktop:~$

Then i tried downloading the package called xorg-input-wizardpen-0.8.1.tar.gz
So, i extracted it in my home, and moving into the new directory i executed ./configure --with-xorg-module-dir=/usr/lib/xorg/modules

This was the end of the answer:
(code)
configure: error: Package requirements (xorg-server >= 1.0.99.901 xproto ) were not met:

No package 'xorg-server' found
No package 'xproto' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XORG_CFLAGS
and XORG_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I installed x11proto-core-dev

and now the "No package 'xproto' found" message isn't there, but it still gets stuck because of the xorg-server
What do i do?
