I had the same issue. Download the latest version of LWJGL from http://lwjgl.org/download.php . After extracting that,

1. Copy the updated lwjgl.jar, lwjgl_util.jar, and jinput.jar from the lwjgl/jar folder into the <ftb_mod_folder>/minecraft/bin folder
2. Copy all of the files from the lwjgl/native/linux folder into the <ftb_mod_folder/minecraft/bin/natives folder
