neovim fails to compile with Symbol not found: _cur_term

The new neovim port fails to compile, ending with this in main.log:

Could be related? ​​https://github.com/neovim/neovim/issues/2033#issuecomment-75364945 "This error happens when libtermkey fails to find unibilium and tries to link against libterminfo"

[aaron@…]

Removing and recompiling libtermkey from source resolves the problem:

port uninstall libtermkey
port install -s libtermkey

I suspect this means that the pre-compiled package for libtermkey was built without a depdency on unibilium?

[aaron@…]

Now I'm confused. The patch-Makefile for libtermkey explicltly removes the unibilium dependency, in favor of ncursesw?

I was confused as well. The port builds fine for me on my local system, but ​failed on the yosemite buildbot.

I just noticed the missing dependency on ncurses in libtermkey. Fixed in r143099.

Please test again.

Both libtermkey and neovim now install from packages without trouble. Recompiling neovim with the pre-built libtermkey package also works. Thank you!
