It seems like on Fedora 16 cabal isn't able to install scion-browser from hackage because of some incompatibilities with respect to Fedora's shared objects.

When I run cabal install scion-browser I get:

...
Loading package terminfo-0.3.2.3 ... <command line>: can't load .so/.DLL for:
   ncursesw (/usr/lib64/libncursesw.so: file too short)
cabal: Error: some packages failed to install:
scion-browser-0.2.8 failed during the building phase. The exception was:
ExitFailure 1

I already have all packages installed for ncurses and the required file exists, but it's not a binary or symbolic link and thus the installation fails:

bash-4.2$ cat /usr/lib64/libncursesw.so 
INPUT(libncursesw.so.5 -ltinfo)

I don't think replacing that file with a symbolic link to libncursesw.so.5 would be a great idea, but I can't think of any other way in order to get it installed. What should I do, please?

As described here, GCC and GHC don't necessarily follow links in the same way. The fixed described worked for me. 

cd /usr/lib
sudo mv libncurses.so libncurses.so.bak
sudo mv libncursesw.so libncursesw.so.bak
sudo ln -s /lib/libncurses.so.5 libncurses.so
sudo ln -s /lib/libncursesw.so.5 libncursesw.so

Since I was on a 64 bit Fedora box, I was moving things around in /lib64 and /usr/lib64
