Just tried the latest in master, and there is a new problem.  I'm
working on this all day today, ping me on jabber or
irc://irc.freenode.net/guardianproject (_hc) if you would to work on
this or help setting up the Android NDK cross-building environment.  Its
really straightforward to setup on Debian, Ubuntu, and Mac OS X,
especially compared to other cross-compilers I've worked with.

Here's the build error:
