What steps will reproduce the problem? 1. ./configure --prefix=/usr 2. make 3. sudo make install

What is the expected output? What do you see instead? VTG should install docs into /usr/share/doc/vtg/ due to:

--datarootdir=DIR by default == [PREFIX/share] --docdir=DIR by default == [DATAROOTDIR/doc/vtg]

But it installs into /usr/doc/vtg/, which is deprecated.

What version of the product are you using? On what operating system? I'm using vtg-0.12.0.0-beta2.tar.bz2 on my Gentoo Linux amd64.

Please provide any additional information below. I'm actually writing an ebuild for vtg, so the reason I ever discovered this is a message in my almost finished ebuild:

QA Notice: This ebuild installs into the following deprecated directories:

usr/doc

Setting --docdir to anything doesn't make any effect either.
