I don’t know whether some recent updated to another port that previously didn’t 
depend on it now does, but here’s what it is, and below, what depends on it.

ghc @9.4.4_1 (lang, haskell)

Description:  The Glasgow Haskell Compiler is a robust, fully-featured,
  optimising compiler and interactive environment for
  Haskell 98, GHC compiles Haskell to either native code or
  C. It implements numerous experimental language extensions
  to Haskell 98, for example: concurrency, a foreign
  language interface, multi-parameter type classes, scoped
  type variables, existential and universal quantification,
  unboxed types, exceptions, weak pointers, and so on. GHC
  comes with a generational garbage collector, and a space
  and time profiler.

What is "ghc" and why was it installed?

[Fielding, Eric J (US 329A) via macports-users]

I was running “port selfupdate” and “port upgrade outdated” for the first time 
in a while, and I noticed that my Intel MacBook Pro was spending almost an hour 
compiling a port called “ghc” that I don’t remember seeing before and I am sure 
I did not request. Is this part of something else that was added recently that 
is now a dependency of some other port?

Thanks,
++Eric
