If you have trouble getting a stratum proxy running, you can point the cube miner(s) at Ozcoin. They still support the Getwork protocol via a Stratum proxy that they run for you.
Go to OzCoin, set up an account. Set up a worker and password for each cube and set up the cube to point to the OzCoin Stratum Proxy in US or in EU.
Then while you are banking some shares with OzCoin, figure out how to get a local Stratum proxy going on your Mac or other machine. Once you have the the local Stratum proxy you will be able to max out your cube hash rate over-clocked at 35 to 40 GH and get faster/sooner payouts form one of the larger mining pools or switch to the OzCoin stratum pool if you like it.
From OzCoin;
Stratum proxy for older (getwork) mining software that does not support stratum, please upgrade if possible
USE FOR getwork based ASIC hardware eg: Block eruptors and Bitfury
