On two ~amd64 systems i get a compile error. Reproducible: Always Steps to Reproduce: 1. emerge -avt games-simulation/crrcsim 2. See the error Actual Results: emerging stopped Expected Results: Nicely installed simulator ;-) A small portion of the error: crrcsim-winddata3D.o: In function `_ZNK4CGAL19Cartesian_converterINS_21Type_equality_wrapperINS_27Cartesian_base_no_ref_countIdNS_15Filtered_kernelINS_16Simple_cartesianIdEELb1EEEEES6_EENS4_INS_4GmpqEEENS_12NT_converterIdS9_EEEclERKNS_7Point_3IS6_EE.clone.453': winddata3D.cpp:(.text+0x245): undefined reference to `__gmpq_init' winddata3D.cpp:(.text+0x29b): undefined reference to `__gmpq_set_d' winddata3D.cpp:(.text+0x2c2): undefined reference to `__gmpq_init' winddata3D.cpp:(.text+0x317): undefined reference to `__gmpq_set_d' winddata3D.cpp:(.text+0x33e): undefined reference to `__gmpq_init' winddata3D.cpp:(.text+0x393): undefined reference to `__gmpq_set_d' crrcsim-winddata3D.o: In function `CGAL::Handle_for<CGAL::Gmpq_rep, std::allocator<CGAL::Gmpq_rep> >::~Handle_for()': winddata3D.cpp:(.text._ZN4CGAL10Handle_forINS_8Gmpq_repESaIS1_EED2Ev[_ZN4CGAL10Handle_forINS_8Gmpq_repESaIS1_EED5Ev]+0x18): undefined reference to `__gmpq_clear' crrcsim-winddata3D.o: In function `boost::operator*(CGAL::Gmpq const&, CGAL::Gmpq const&)': winddata3D.cpp:(.text._ZN5boostmlERKN4CGAL4GmpqES3_[boost::operator*(CGAL::Gmpq const&, CGAL::Gmpq const&)]+0x2d): undefined reference to `__gmpq_init' winddata3D.cpp:(.text._ZN5boostmlERKN4CGAL4GmpqES3_[boost::operator*(CGAL::Gmpq const&, CGAL::Gmpq const&)]+0x44): undefined reference to `__gmpq_mul' crrcsim-winddata3D.o: In function `boost::operator-(CGAL::Gmpq const&, CGAL::Gmpq const&)': winddata3D.cpp:(.text._ZN5boostmiERKN4CGAL4GmpqES3_[boost::operator-(CGAL::Gmpq const&, CGAL::Gmpq const&)]+0x2d): undefined reference to `__gmpq_init' winddata3D.cpp:(.text._ZN5boostmiERKN4CGAL4GmpqES3_[boost::operator-(CGAL::Gmpq const&, CGAL::Gmpq const&)]+0x44): undefined reference to `__gmpq_sub' #emerge -pqv games-simulation/crrcsim-0.9.11 [ebuild N ] games-simulation/crrcsim-0.9.11 USE="-portaudio" Files will be attached later.

I can confirm this problem, One quick fix is USE="-gmp" emerge -av1 sci-mathematics/cgal ; emerge -av crrcsim if you don't need sci-mathematics/cgal[gmp] I try to fix this.
