[xmonad] Lost XFT font support after updating Xmonad

In the process of compiling the latest Xmobar from git, I needed to update my version of GHC to 7.0.4. While I was at it, I also updated my Xmonad to 0.10. Everything seems to run fine, but I lost the XFT font support (e.g. in Xmobar and in tab titles on tabbed layouts). Can anyone suggest a solution to bring XFT fonts back? I upgraded with something like cabal update cabal install xmonad cabal install xmonad-contrib --flags="-use_xft" cabal configure xmobar --flags="-with_xft" cabal install xmobar
