[xmonad] default gap not working anymore

[lobzang at free.fr]

Hello,

I recently upgraded and noticed that default gap (to use for status bar) does
not compile anymore. Did I miss something ?

xmonad.hs:150:10: Not in scope: `modifyGap'
xmonad.hs:150:38: Not in scope: `XMonad.defaultGaps'
xmonad.hs:296:8: Not in scope: `defaultGaps'


Thank you,

Lobzang
