Clojure failing to compile jackknife

Question

As a clojure noob, I am trying to use cascalog to parse a large CSV file. Here is my minimal project.clj:

(defproject org.example/sample "1.0.0-SNAPSHOT"

  :description "extract fields from a certain csv file."
  :dependencies [
    [cascalog "2.0.0"]
    [clojure-csv/clojure-csv "2.0.1"]
  ]

  :profiles { :dev {:dependencies [[org.apache.hadoop/hadoop-core "1.1.2"]]}}

  :jvm-opts ["-Xms768m" "-Xmx768m"]

)

lein deps succeeds, but when I run (use 'cascalog.api) inside lein repl, then I get the following error:

CompilerException java.lang.RuntimeException: Unable to resolve symbol: combinations in this context, compiling:(jackknife/seq.clj:12)

Removing clojure-csv from project.clj prevents the error, but I can run (use 'clojure-csv.core) inside lein repl without error.

One other person on the internet appears to have had this problem, but has not posted a solution. What is going on here, and how should I fix it? I'd be eternally grateful if someone could help.
