 The ticket is a followup of https://trac.macports.org/ticket/73754

 {{{ghc}}} fails to build because the symbol changes made to {{{ghc-
 prebuilt}}} in ​https://github.com/macports/macports-
 ports/commit/7704d783cdeb79174e270b0712d94a64f64c8d0d are incompatible
 with the existing {{{hadrian}}} setting
 {{{
 stage0.*.ghc.link.opts += -L${configure.sdkroot}/usr/lib
 }}}
 which specifies that the stage 0 compiler link against the SDK
 {{{libiconv}}} symbols used in the unmodified {{{ghc-prebuilt}}} compiler.
 Error:
 {{{
 :info:build Undefined symbols for architecture x86_64:
 :info:build   "_libiconv", referenced from:
 :info:build       _hs_iconv in libHSghc-
 internal-9.1401.0-53af.a[6](iconv.o)
 :info:build   "_libiconv_close", referenced from:

 )
 :info:build ld: symbol(s) not found for architecture x86_64
 :info:build clang: error: linker command failed with exit code 1 (use -v

 invocation)
 }}}

 Setting
 {{{
 stage0.*.ghc.link.opts += -L${prefix}/lib
 }}}
 fixes this issue, in addition to keeping the potentially useful symbol
 changes in {{{ghc-prebuilt}}} to MacPorts {{{libiconv}}} that may address
 future {{{ghc}}} compiling issues.

 I will post a PR.
