Warnings in mix.exs

[Fl4m3Ph03n1x]

When compiling I get the following warnings:

warning: variable "package" does not exist and is being expanded to "package()", please use parentheses to remove the ambiguity or change the variable name
  /home/admanmedia/Workspace/admanmedia/clint/deps/rop/mix.exs:12

warning: variable "deps" does not exist and is being expanded to "deps()", please use parentheses to remove the ambiguity or change the variable name
  /home/admanmedia/Workspace/admanmedia/clint/deps/rop/mix.exs:14

While true this is not critical, it is rather annoying.
Then there is also the fact that my team may choose against using this library because it gives the impression it is not being maintained.

Do you accept PRs?
