Hey Andrew,

I'm getting the same error..
Did you figure out the problem?

Thanx, Goran

Hmm not sure. I use RVM and homebrew if that's any help.

Yeah, I use RVM too but not homebrew.
I'm getting this error on crunchbang linux,
but not on the the Mac where don't use RVM.

I this page look at the last comment:
http://stackoverflow.com/questions/2729865/fix-an-external-dependency-of-a-ruby-gem
Ken Bloom says:
"His compile errors refer to structs in the Ruby interpreter, not in the ncurses library."

Do you still get this error?

Yeah I did get it installed. Can't remember what I was doing wrong at the time. This was on OS X by the way.
