I'm having a problem with building walls – some of my walls are suspend before they can be built. The suspension message is that there's a creature occupying the site. I've been watching and a dwarf will enter the space that the wall is to be built in, stand there for a while, I'd assume trying to build the wall, and then suspend the construction… so I think the builders themselves are the creatures in the way of building? Is that possible? How do I fix that?
Here's the layout:
X = built wall
0 = unbuilt problem wall
~ = water tile
_ = empty dirt tile
~_____________
~0__XXXX0XXXXX
~X____________
~X____________

This is a problem with the current version of the game (v0.34.11 as of this writing) and usually happens when the tiles around the place you want to build the wall are walkable, but can't be built from. One such example are ramps.
In your case it's more likely that the path finding gets the Dwarf to build the wall from the "wrong" side (one which triggers the error; usually north). Try those steps:
