[xmonad] xmonad: xmonad-extras 0.12 fails to build

[Dave Macias]

This is my first time posting here so i hope im doing this right.
Just updated ghc to 7.10.1 and had to rebuild xmonad, xmonad-contrib, and
xmobar.
I also use xmonad-extras but it failed during the build. I tried using
cabal and also from source but both give same output:

$ cabal install xmonad-extras

ExitFailure 1


I got to look at the log but it just has what i pasted above. System is
Arch 3.19.2-1-ARCH

Any input is appreciated.
Thanks
