Comment (by stusmith):

 Also in `cabal install diagrams`:

 {{{
 [2 of 5] Compiling Graphics.Svg.Core ( src/Graphics/Svg/Core.hs,
 dist/build/Graphics/Svg/Core.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.8.4 for x86_64-unknown-linux):
         Simplifier ticks exhausted
     When trying UnfoldingDone
 base:Foreign.Storable.$fStorableWord8_$cpokeByteOff{v r2gn} [gid]
     To increase the limit, use -fsimpl-tick-factor=N (default 100)
     If you need to do this, let GHC HQ know, and what factor you needed
     To see detailed counts use -ddump-simpl-stats
     Total ticks: 34200
 }}}

 (On Ubuntu server 15.10).

 Output from `-ddump-simpl-stats` is attached as `diagrams-dump-simpl-
 stats.txt`.
