The unbuffer command is classified by the build system as an example, which the ebuild decides to wipe out unconditionally, but from what I've seen it is generally considered to be a part of the expect package. I've found a few cases of Gentoo people looking for unbuffer on the internet, and the response from others is generally something like "If expect does not install it then the Gentoo package is broken". This has been previously mentioned as an issue in bug 536414.
I agree, for now I have needed to rely on building this with doc USE flag and manually uncompressing the installed copy
