Comment (by J.Gilbey@…):

 Well, I'm still trying to build pandoc on OS X Yosemite, and it's proving
 to be very tricky indeed.

 This is a log of how far I've got and where I've got stuck:

 The current pandoc port no longer builds, as it depends on an out-of-date
 hs-text and other packages which have not been ported.

 So I tried updating packages one at a time to get pandoc to build - until
 I hit a brick wall.

 I have applied the patches described in tickets #46464, #46484, #46485,
 #46486, #46487 and #46488.

 The following new packages are also required, and Portfiles are attached
 to this report:

 hs-juicypixels
 [http://hackage.haskell.org/package/JuicyPixels-3.2.2/JuicyPixels-3.2.2.tar.gz]

 hs-scientific
 [http://hackage.haskell.org/package/scientific-0.3.3.5/scientific-0.3.3.5.tar.gz]

 But then I got stuck, because the following packages included in haskell-
 platform are too old and need to be updated:

 hs-attoparsec: The version in haskell-platform is too old for the current
 aeson (which is needed) to build :-(  A tentative Portfile for a stand-
 alone port is attached.

 hs-text: The version in haskell-platform is too old for the current hs-
 attoparsec.  Portfile for stand-alone version attached.

 But when I try building hs-attoparsec using the new version of hs-text, it
 dies because it's trying to look for the old version, or something like
 that - log files attached.

 I don't know what to do now :-(
