Linux launcher core dumps on Gentoo

Hi folks,
I recently did an emerge -vaNDuq --with-bdeps=y world on my Gentoo system and now the launcher won’t start. I’ve tried recompiling everything and it’s just not going. I’ll post the stack trace below from the terminal in hopes that someone can help me identify what is going awry here. Please let me know if you’ve encountered similar issues or can guess what the issue might be - I haven’t been able to log in for almost a week now on this system.

[end of stack trace]
Calling _exit(1). Core file will not be generated.

Any ideas would be appreciated. Thanks!

I fixed this by enabling the osmesa use flag on the media-libs/mesa package. w00t!
