I am trying to install hakyll in a cabal sandbox, but somehow it doesn't<br>
work. Here's what I am doing:<br>

Then I tried (inside the sandbox):<br>
<br>
> $ cabal install cabal-install<br>
<br>
which installed cabal 1.24.0.0 into the sandbox. Now, when I am using<br>
it, I am getting different errors:<br>

What is going on here? Why am I getting different errors with the new<br>
cabal version?<br>
What is the relationship between system-wide packages and those in the<br>
sandbox? I thought sandbox is meant to be an isolated environment?!?<br>
<br>
How do I get the list of all the packages currently installed in the<br>
sandbox? Is this:<br>
<br>
$ ls ./lib/x86_64-linux-ghc-7.6.3/<br>
async-2.1.0 ed25519-0.0.5.0 parsec-3.1.11<br>
base16-bytestring-0.1.1.6 hackage-security-0.5.2.1 random-1.1<br>
base64-bytestring-1.0.0.1 HTTP-4000.3.3 stm-2.4.4.1<br>
bytestring-builder-0.10.8.1.0 mtl-2.2.1 tar-0.5.0.3<br>
Cabal-1.24.0.0 network-2.6.3.1<br>
transformers-0.5.2.0<br>
cryptohash-sha256-0.11.100.1 network-uri-2.6.1.0 zlib-0.6.1.1<br>
<br>
the way? Why is 'base' not on the list, although the new cabal is not<br>
complaining about it anymore?<br>
<br>
This is the latest Debian stable.<br>
<br>
Thanks!<br>
