[Linux] Black screen because of liblwgl.so

[Gankachi]

I finished setting up the last version of Linux Mint 15 yesterday, and I worked on Minecraft and FTB today. Minecraft 1.5.2 worked perfectly, but after I launched FTB Ultimate 1.1.3, I got the FTB intro, and the screen went black. On the Console, I had this:

Seems like this happened:
FMLRelauncher.relaunchApplet:287->MinecraftLauncher.main:217: Unhandled error launching minecraft: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

I played the game yesterday on windows (I have a hybrid computer) and it worked perfectly. Among all this Java ununderstandable gibberish, I found also this:
Caused by: java.lang.UnsatisfiedLinkError: Can't load library: /host/Users/Kévin/AppData/Roaming/.FTB/Unleashed/minecraft/bin/natives/liblwjgl.so
If I'm not mistaken, it would mean that liblwjgl.so can't be load. Is there anyway I could fix this problem?

Thanks in advance,
Gankachi

Update LWJGL to 2.9.

This will need to be done for every modpack after every update.
