Comment(by kitchen.andy@…):

 Replying to [comment:37 cal@…]:
 > I'm attaching the Portfile with some modifications (you don't have to
 define some of the variables in phases explicitly).
 Thanks!

 > I think the value of having a current ghc outweighs the `dblatex`
 problem, so I'm probably going to commit this soon. The easiest way to
 disable building PDF/PS documentation would probably be to patch
 `configure.ac` to always set `BUILD_DOCBOOK_PS=NO` and
 `BUILD_DOCBOOK_PDF=NO` (lines 778 and following), but maybe instead of
 disabling building the documentation we should fix the problem with
 building it.
 Sure, I like the idea of fixing it, although this is entirely outside of
 my expertise, I literally know nothing about any of those tools,
 perhaps I could ask on the haskell mailing list/IRC channel. I'll try and
 do this (at least the patch) over the weekend...

 In your opinion is using that patch as opposed to wiping
 doc/user_guide/ghc.mk
 worth the dependency on autoconf? Or is that dep implicit?

 > Do you want to be listed as maintainer for this port? If yes, please
 state which email address you want me to put into the Portfile. Also
 please decide whether you want openmaintainer to be added (as described in
 http://guide.macports.org/#project.update-policies).
 Sure, that sounds great, kitchen.andy+macports at gmail.com would be my email
 address. adding openmaintainer would be best.

 > I'm not sure what to do with the ghc-devel port. I guess leaving it
 around with the older version isn't the way to go, so I'd probably make it
 a stub port and mark it `replaced_by` ghc.

 In the next few weeks I'd like to do a ghc-devel port for 7.5, mainly in
 preparation for 7.6 which has a lot of features
 that I am excited about (deferred type errors and holes). The current
 nightly seemed to compile from source
 with no babysitting, so touch wood, it should be straight forward.
