The HEAD and several other packages travel together: if you update one you must update the others.

http://hackage.haskell.org/trac/ghc/wiki/Commentary/Libraries

In this case you need to update template-haskell.

|
| I was getting errors somewhere in haddock about some ambiguous
| function, so I did a darcs pull to see if that would pull in a fix for
| the problem (unfortunately I didn't make a note of the errors).
|
| But now the compile fails earlier with errors in deSugar/DsMeta.hs:
|
| deSugar/DsMeta.hs:471:48:
|     Not in scope: type constructor or class `TH.InlineSpecQ'
|
| deSugar/DsMeta.hs:504:16:
|     Not in scope: type constructor or class `TH.TyVarBndr'
|
| deSugar/DsMeta.hs:538:50:
|     Not in scope: type constructor or class `TH.TyVarBndr'
|
| deSugar/DsMeta.hs:640:29:
|     Not in scope: type constructor or class `TH.Kind'
|
| etc.
|
| Is the code in darcs supposed to be compilable normally?
|
| And what can I do about such situations? Just report them here?
