I tried to install svg-builder by "cabal install svg-builder"and got the
following error:
Resolving dependencies...

Building svg-builder-0.1.0.1...
Preprocessing library svg-builder-0.1.0.1...

ghc: panic! (the 'impossible' happened)
(GHC version 7.8.4 for x86_64-unknown-linux):
Simplifier ticks exhausted

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
I tried again with ghc -fsimpl-tick-factor=300 and it worked.
