It fails to compile with several fatal error: Eigen/Core Looking at flags.make files there is no -I/usr/include/eigen3 since Gentoo installs the Eigen headers there. Furthermore it tries to compile an internal version of Eigen which also fails.
On my system emerge --info eigen says: dev-cpp/eigen-2.0.17::gentoo was built with the following: USE="-debug (-doc) -examples" ABI_X86="64" dev-cpp/eigen-3.2.8-r2::gentoo was built with the following: USE="openmp (-altivec) -debug -doc -test" ABI_X86="64" CPU_FLAGS_X86="sse2 sse3 sse4_1 sse4_2 ssse3" My blender-2.78 build.log has -- Found Eigen3: /usr/include/eigen3 in the configuration phase and includes the header using lines with -isystem /usr/include/eigen3 It also seems to compile the internal version of eigen successfully. Could you please provide the build.log and emerge --info for blender and eigen and I will look further into this.

I just noticed that I had an additional copy of Eigen3 on /usr/local/include. When I rename this, blender does install. Is there any mean to disable blender searching /usr/local/include ? Sorry for the noise, Helmut
I haven't tried it out, but looking at build_files/cmake/Modules/FindEigen3.cmake you can set EIGEN3_ROOT_DIR to choose which version of eigen3 you wish to use. So perhaps this will work for you # export EIGEN3_ROOT_DIR="/usr/include/eigen3" # emerge blender To make it permanent you can patch the blender-2.78.ebuild to include a line in the local mycmakeargs defined in src_configure() -DEIGEN3_ROOT_DIR="/usr/include/eigen3" It should also be possible to patch FindEigen3.cmake to remove the /usr/local from the _eigen3_SEARCH_DIRS
