Не получается откомпилировать pgAdmin

Здравствуйте! Помогите пожалуйста
Стоит Калькулейт Гном.
Установил PostgreSQL 9.1.1, потом pgAdmin но как оказалось в Portage находиться старая версия которая ругается на не совместимость с этой версией Постгреса.
Скачал на оф. сайте последнюю версию pgAdmin пытаюсь установить по инструкции:

You will need:

- A modern development environment: 

    - GTK 2.2 or above.
    - GNU automake 1.9 or above.
    - GNU autoconf 2.59 or above.
    - GNU gcc 3.4 or above.

- wxGTK 2.8.x from http://www.wxwidgets.org/
- libxml2 2.6.18 or above from http://www.xmlsoft.org/
- libxslt 1.1.x or above from http://www.xmlsoft.org/
- PostgreSQL 8.4 or above from http://www.postgresql.org/

Building:

1) Install libxml2 and libxslt if they are not already present on your system, 
   per the instructions included with them.
   
2) Install PostgreSQL per the instructions included. It is recommended that you
   build with OpenSSL support, using the --with-openssl configure option.
   
3) Unpack the wxGTK tarball to a convenient location, and build and install it
   as follows:
   
     cd /path/to/wxGTK/source/
     ./configure --with-gtk --enable-gtk2 --enable-unicode
     make
     sudo make install

     # Install wxWidgets contrib modules.
     cd contrib/
     make
     sudo make install
	
   A script is included in the pgAdmin source tarball 
   (xtra/wx-build/build-wxgtk) which will build and install wxWidgets in each 
   combination of shared/static/debug/release builds for you.
   
4) Unpack the pgAdmin tarball to a convenient location, and build and install it 
   as follows:
   
     bash bootstrap	# Required only if building from an SVN checkout
     ./configure
     make all
     sudo make install
	 
   If any of the prerequisite components are installed in locations that the 
   configure script cannot find, you may specify their locations on the command
   line. See the configure help (./configure --help) for details.

Выполнение команды,

./configure --with-gtk --enable-gtk2 --enable-unicode

прерывается ошибкой

checking wxWidgets version... failed
configure: error: The version of wxWidgets required (2.8) is not supported by the installations in /usr.

Что нужно сделать, подскажите пожалуйста?
