On the wiki page for requisites needed for Ubuntu 14.04 a space is deleted between 2 packages,libiberty-de and libxt-dev, giving an error that libib-dev is not found.
sudo apt-get install git-core build-essential binutils-dev cmake flex \ bison zlib1g-dev qt4-dev-tools libqt4-dev libncurses5-dev libiberty-dev\ libxt-dev rpm mercurial graphviz

This bug can be closed. I fixed this on the 4th of February 2015. And according to what I could figure out, it was my fault... somehow I didn't notice the missing space :(
@Peter: This issue was on the openfoamwiki.net, so you could have registered on the wiki and edited the pages yourself ;)
