amule安装问题

以下为本人装amule时./configure报错，我不知道wx-config这个命令是怎么回事，有那位知道吗，所缺的两个包都已安装，
wxBase-2.6.1.tar.gz
wxGTK-2.4.2.tar.bz2
aMule-2.2.1.tar.bz2  
都是在http://sourceforge.net/下载的

configure: error:
    The requested wxWidgets build couldn't be found.
   
    The configuration you asked for aMule requires a wxWidgets
    build with the following settings:
        --unicode=yes
    but such build is not available.

    To see the wxWidgets builds available on this system, please use
    'wx-config --list' command. To use the default build, returned by
    'wx-config --selected-config', use the options with their 'auto'
    default values.

    If you still get this error, then check that 'wx-config' is
    in path, the directory where wxWidgets libraries are installed
    (returned by 'wx-config --libs' command) is in LD_LIBRARY_PATH
    or equivalent variable and wxWidgets version is 2.8.0 or above.
