Actually a dependency on gcc >= 6.x was needed. Eigen "built" fine
with gcc 5, but eigen being a header-only library, it doesn't build
anything. However, gtkiostream would definitely not build with gcc 5.x
using the updated eigen. So I increased the dependency to be gcc >= 6
and applied.

This should have been just 3 dashes, i.e "---" in order to be
understood by Git as "what follows isn't part of the commit message".
