Followup-For: Bug #758310
neovim should better check (maybe through pkg-config) which
version of libuv it is building against.
Debian is currently only shipping the stable branch 0.10,
while from your report I seem to understand that neovim is
instead using the 0.11 development branch.
Please note that 0.11 is just a stabilizing branch for the
forthcoming 0.12, and both are not API compatible with 0.10.
As it involves a soname bump and a new packages through NEW,
the experimental 0.11 will never be part debian.
However, the 0.12 release is approaching  and there are plans
to have both 0.10 and 0.12 versions shipped with jessie .
