+### Please describe the problem.
+I'm trying to get an Android development environment set up, but I am running into conflicting library versions inside of the chroot. The package installation script now finishes, but I run into a link-time error during `cabal configure` because it is pulling in two different versions of the unix package for some reason. Please let me know if there is any information I can get from my build environment that would help diagnosing the issue.
+
+### What steps will reproduce the problem?
+Run `buildchroot`, `install-haskell-packages`, `make android`
+
+### What version of git-annex are you using? On what operating system?
+Attempting to build from source, cross-compiling for Android on Debian Jessie.
+
+### Please provide any additional information below.
