### What steps will reproduce the problem?
`stack build`
### What version of git-annex are you using? On what operating system?
e029eb8b, OS X 10.10.5.
### Please provide any additional information below.
These are apparently dependencies of `Setup.hs`. Adding
explicit-setup-deps:
"*": true
to `stack.yaml` [(as described here)](https://github.com/commercialhaskell/stack/blob/a59997d5db963bba403119843340688ee25e2c6f/doc/yaml_configuration.md#explicit-setup-deps)
fixes the error and builds git-annex successfully.
### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
> I tried enabling this, and it broke build on my i386ancient autobuilder,

> both building git-annex and also its dependencies (eg, process):
/usr/bin/ld: cannot find -ltinfo
> Which seems to be libtinfo, part of the ncurses library. Which is weird,
> AFAIK git-annex does not use ncurses at all.

> above error.
