I am trying to install

re2 (Version 0.2016.05.01)

but somehow I get the following error.

make -j9 DESTDIR=/var/tmp/portage/dev-libs/re2-0.2016.05.01/image/ prefix=/usr libdir=$(exec_prefix)/lib64 install
mkdir -p /var/tmp/portage/dev-libs/re2-0.2016.05.01/image//usr/include/re2 /var/tmp/portage/dev-libs/re2-0.2016.05.01/image//usr/lib64/pkgconfig

sed: can't read re2.pc.in: No such file or directory

Is a file missing here?

Thank you for your Feedback.
