I'm running Debian 7 Wheezy Stable (with some packages from unstable)
Inkscape version: Inkscape 0.48.3.1 r9886
This is the output of the install script:
$ sudo ./install es
[sudo] password for user:

Now, just restart Inkscape and you should have the Pages submenu in the Extensions menu. Enjoy!
Do you have an X server started? The install script will try to run inkscape to get the folders, but inkscape will require X. So I recommand that you open an X server first, then open an Xterm and then run the install script.
