Geth console outputs after `admin.setSolc("/usr/bin/solc")`:

    eth.compile.solidity("")
    I0601 15:31:56.663260 common/compiler/solidity.go:114] solc, the solidity compiler commandline interface
    Version: 0.3.3-0/RelWithDebInfo-Linux/g++/Interpreter
    path: /usr/bin/solc
    solc: empty source string
    at web3.js:3119:20

and

    eth.getCompilers()
    []

I am getting an empty array instead of `['Solidity']`. 

Installed solidity through: `sudo apt-get install solc`

output for `which solc`: `/usr/bin/solc` (added this to PATH)

I have seen a similar [question](http://ethereum.stackexchange.com/questions/4102/link-solc-with-geth-problem), but I am using the latest version (0.3.3) and still have the problem. Am I missing anything?
