+I tried to update git-annex via cabal. It fails due to lens not installing:
+
+ juh@sokrates:~$ cabal update
+ Downloading the latest package list from hackage.haskell.org
+ juh@sokrates:~$ cabal install git-annex
+ Resolving dependencies...
+ In order, the following will be installed:
+ lens-4.2 (new version)
+ DAV-0.6.2 (reinstall) changes: http-client-0.3.1.1 -> 0.3.3.1,
+ http-client-tls-0.2.1.1 added, http-types-0.8.4 -> 0.8.5, lens-4.1.2 -> 4.2,
+ network-2.4.1.2 added, optparse-applicative-0.7.0.2 added, xml- conduit-1.2.0.1
+ -> 1.2.0.2, xml-hamlet-0.4.0.8 added
+ git-annex-5.20140707 (new package)
+ Warning: Note that reinstalls are always dangerous. Continuing anyway...

+ Perhaps you meant

+ Failed to install lens-4.2
+ cabal: Error: some packages failed to install:
+ DAV-0.6.2 depends on lens-4.2 which failed to install.
+ git-annex-5.20140707 depends on lens-4.2 which failed to install.
+ lens-4.2 failed during the building phase. The exception was:
+ ExitFailure 1
+
+I am not an experienced user of cabal. So any hints to solve the conflicts are appreciated.
