 Replying to [comment:5 rwbarton]:

 Sorry I don't understand how it can be #10458, can you explain?
 The error I reported
 {{{
 <command line>: can't load .so/.DLL for:

 seeems quite different than the one in #10458:
 {{{

 }}}
 In addition #10458 does not mention regression and it is on Linux. This
 bug is a regression from 7.8.4 and happens on the Mac but not on Linux.
 From https://github.com/haskell-opengl/GLUT/issues/19:

 {{{
 I checked it under GHC 7.8.4 and
 $ ghci -package GLUT
 works fine (loads the package and shows the prompt).
 ...
 OK, so this seems to be unrelated to TH and to the specific Mac OS X
 version. Do you have GHC 7.8.3 or 7.8.4 on your Mac to check if this is a
 GHC 7.10 regression? In the meantime I'll try to get 7.10 running on a
 Mac, but this might take some time, normally I develop on Windows + Linux
 only, so some help would be appreciated.
 ...
 The consensus seems to be that this is a GHC 7.8.4 => 7.10.1 regression
