There were quite a few things in make.conf.example that didn't make sense. I did my best to correct as many of them as I could spot. I'm not sure about the word "extry." It could be a word I've never heard before... But it seems most likely that it should say "entry." I also removed the message stating a default directory size of 2G as it was already mentioned earlier in the same paragraph. Other than those they're pretty clear and simple corrections. Reproducible: Always Steps to Reproduce: 1. 2. 3.

I was unsure which component to associate this with. I realise now that it wasn't baselayout, but portage. I think Applications is the next best place for it, since there is no portage component listed above. If I'm wrong then please correct it for me.
Updated.
Bug has been fixed and released in stable portages on or before 2.0.51-r2
