See <https://bugs.gentoo.org/> for instructions. Line2D is a typedef for Line<float, 2>. I rebuilt the code with clang 3.3 and had no problems with it. I'm attaching the preprocessed file, but I'm available to put the full source code somewhere (it's from an open source project, but the part I'm working on has not been committed yet).
I've pushed it, you can find the full code here: https://bitbucket.org/King_DuckZ/clooneljump/commits/tag/gcc_49_error
this appears to be fixed w/gcc-4.9.1
