Renaming the system-wide libs files results in x86_64-pc-linux-gnu/bin/ld: cannot find -lre2 so it seems the system-wide version does not have the expected API like the copy supposedly buried somewhere inside chromium tarball. Or I am completely wrong. ;)
I think I am right, See this that system re2 is forced in build.log: >>> Configuring source in /mnt/1TB/usr/portage/portage/www-client/chromium-27.0.1453.56/work/chromium-27.0.1453.56 ... build/gyp_chromium --depth=. -Ddisable_sse2=1 -Dlinux_use_tcmalloc=0 -Ddisable_glibc=1 -Ddisable_pnacl=1 -Ddisable_newlib_untar=1 -Dflapper_version_h_file=/mnt/1TB/usr/portage/portage/www-client/chromium-27.0.1453.56/temp/flapper_version.h -Duse_system_bzip2=1 -Duse_system_flac=1 -Duse_system_harfbuzz=1 -Duse_system_icu=1 -Duse_system_jsoncpp=1 -Duse_system_libevent=1 -Duse_system_libjpeg=1 -Duse_system_libpng=1 -Duse_system_libusb=1 -Duse_system_libvpx=1 -Duse_system_libwebp=1 -Duse_system_libxml=1 -Duse_system_minizip=1 -Duse_system_nspr=1 -Duse_system_opus=1 -Duse_system_protobuf=1 -Duse_system_re2=1 -Duse_system_speex=1 -Duse_system_v8=1 -Duse_system_xdg_utils=1 -Duse_system_zlib=1 -Duse_system_ffmpeg=1 -Duse_system_mesa=1 -Duse_system_yasm=1 -Dmedia_use_libvpx=0 -Duse_cups=1 -Duse_gconf=0 -Duse_gnome_keyring=0 -Dlinux_link_gnome_keyring=0 -Dlinux_use_libgps=0 -Dlinux_link_libgps=0 -Duse_kerberos=0 -Duse_pulseaudio=0 -Dselinux=0 -Dlinux_link_gsettings=1 -Dlinux_link_libpci=1 -Dlinux_link_libspeechd=1 -Dusb_ids_path=/usr/share/misc/usb.ids -Dlinux_sandbox_path=/usr/lib64/chromium-browser/chrome_sandbox -Dlinux_sandbox_chrome_path=/usr/lib64/chromium-browser/chrome -Dlinux_use_gold_binary=0 -Dlinux_use_gold_flags=0 -Dproprietary_codecs=1 -Dgoogle_api_key=AIzaSyDEAOvatFo0eTgsV_ZlEzx0ObmepsMzfAc -Dgoogle_default_client_id=329227923882.apps.googleusercontent.com -Dgoogle_default_client_secret=vgKG0NNv7GoDpbtoFNLxCUXu -Dtarget_arch=x64 -Dwerror= I don't see IUSE=re2 so it seems I will have to uninstall my system-wide re2 at least temporarily until I compile chromium. :(
I unmerged dev-libs/re2-9999 but www-client/chromium-27.0.1453.56 required it to be be installed again, although current svn/cvs/git checkout was made. However, the linking failed in the very same step again. So, it looks I can't do more for you here and maybe there is no a built-in copy of re2 inside chromium sources at all.

Please use the version from portage - feel free to reopen if it still fails.
