Mac OS X users: miniupnpc is currently outdated on MacPorts. An updated Portfile is provided in contrib/miniupnpc within this project.

A warning for people using the *static binary* version of Bitcoin on a Linux/UNIX-ish system (tl;dr: **Berkely DB databases are not forward compatible**).
-The static binary version of Bitcoin is linked against libdb4.7 or libdb4.8 (see also `this Debian issue`_).
+The static binary version of Bitcoin is linked against libdb4.8 (see also `this Debian issue`_).
Now the nasty thing is that databases from 5.X are not compatible with 4.X.
significant hassle!

+Ubuntu 11.10 warning
+====================
+
+Ubuntu 11.10 has a package called 'qt-at-spi' installed by default. At the time of writing, having that package
+installed causes bitcoin-qt to crash intermittently. The issue has been reported as `launchpad bug 857790`_, but
+isn't yet fixed.
+
+Until the bug is fixed, you can remove the qt-at-spi package to work around the problem, though this will presumably
+disable screen reader functionality for Qt apps:
+
+::
+
+ sudo apt-get remove qt-at-spi
