[Linux] kde-config not found !

If you stuck with this error :

'The important program kde-config was not found! Please check whether you installed KDE correctly." 

Nothing to worry about, it's simple to fix it. This error happens because on KDE 4, kde-config is renamed to kde4-config. To fix the error, follow these steps :

1. Enter /usr/bin
2. Copy or rename (not recommended) kde4-config into kde-config. I suggest to copy it into kde-config, just type cp kde4-config kde-config

Good Luck !
