Hi,
I managed to build the 0.3.1 client on Ubuntu-14.04 (i586), but it is seriously unstable.
After starting it, it instantly goes to 100% CPU and stays there. The console reports varying connection counts, and the p2p.log shows lots of
20140815T093416.678613 th_a on_blockchain_item_i ] sync: 191d0c7973d0bf89568668600c8b5a36d8938028 node.cpp:1942
According to get_info, the block count stays constant for a long time before it starts to crawl upwards - if it ever gets to that point. Most of the time, it crashes either with an Assertion Failure (attempt to free a mutex while threads are waiting on it) or a segfault. After about a dozen or so attempts I'm now synced up to block #23190. IOW, the client is unusable.
Here's a backtrace of the latest segfault:
--- there are now 4 active connections to the p2p network

I also managed to build the QT wallet, but tested it only briefly as it doesn't even get to the point of opening a "real" window (other than the splash screen). One strange thing I noticed is that it uses "$HOME/BitShares X" instead of "$HOME/.BitSharesX" like the CLI version.
Edit: here's the assertion failure I was referring to:
(wallet closed) >>> bitsharesxd: /home/peter/Work/packages/bitshares/trans/bitsharesx-0.3.1/libraries/fc/src/thread/mutex.cpp:22: fc::mutex::~mutex(): Assertion `!m_blist && "Attempt to free mutex while others are blocking on lock."' failed.
