[Haskell-cafe] Building regex-tdfa-1.1.1 documentation

[j.romildo at gmail.com]

Hello.

I want to build regex-tdfa-1.1.1 haddock documentation locally, but the
procedure fails:

$ ./setup haddock
Preprocessing library regex-tdfa-1.1.1...
Running Haddock for regex-tdfa-1.1.1...
Warning: The documentation for the following packages are not installed. No
links will be generated to these packages: rts-1.0

Text/Regex/TDFA/Common.hs:106:25:
    parse error on input `-- ^ identity of Position tag to set during a transition
-- | Internal use to indicate type of tag and preference for larger or smaller Positions'

$ haddock --version
Haddock version 2.4.2, (c) Simon Marlow 2006
Ported to use the GHC API by David Waern 2006-2008


Any clues?
