it would appear that the launcher isnt downloading the correct LWJGL and natives, while it does get the linux natives , it doesnt grab the linux 64-bit ones when using a 64-bit java, at least for java 1.7
main reason i can tell this , "wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)" appears right after LWJGL tries to load the linux native.
crash report
hope you can fix it though untill then just have ppl download the newest LWJGL from their site and copy over the natives and the jars , as when i just replaced the natives the normal jars complain that they cant find their proper natives.
tested on FTB launcher 1.0.4
