I'm getting the following error

$ cabal install
[1 of 2] Compiling Text.Regex.TDFA.Text ( Text/Regex/TDFA/Text.hs, dist/build/Text/Regex/TDFA/Text.o )

Text/Regex/TDFA/Text.hs:41:10: error:
    Duplicate instance declarations:
      instance Extract T.Text -- Defined at Text/Regex/TDFA/Text.hs:41:10
      instance [safe] Extract T.Text
        -- Defined in ‘Text.Regex.Base.RegexLike’
   |

   |          ^^^^^^^^^^^^^^
Failed to install regex-tdfa-text-1.0.0.3

The error is due to regex-base 0.94.0.0 added the instance (see here)

-- | @since 0.94.0.0
instance Extract ST.Text where
  before = ST.take; after = ST.drop; empty = ST.empty

Blocking agda/agda#3725.

Fixed compilation.

The error is due to the incompatibility between regex-base 0.94.0.0
and regex-tdfa-text (see
hackage-trustees/regex-tdfa-text#2).

for the record: respective revisions were applied already (see e.g. http://hackage.haskell.org/package/regex-tdfa-text-1.0.0.3/revisions/) so cabal's solver shouldn't run into a plan that results in this compile failure anymore
