 DoCon @2.11 doesn't build anywhere:

 https://build.macports.org/builders/ports-
 11_arm64-builder/builds/97926/steps/install-port/logs/stdio

 {{{
 Warning: docon.cabal:13:18:
 unexpected '.'
 expecting space, white space, opening paren, operator, "," or end of input
 Error: Setup: Failed parsing "./docon.cabal".
 }}}

 Attached is a patch attempting to update the port to 2.12 which fails with
 the same error.

 This port uses ghc; some expert in Haskell packaging is probably needed to
 make sense of this.
