[lldb-dev] LLDB buildbot state

> I've not been looking at the linux one.  However, I am in the process of fixing something in llvm that is broken due to unexpected interactions between libedit, libbsd and <bsd/stdlib.h> on Ubuntu (and probably other linux variants that might implement libedit in terms of libbsd).

The problem here is that any Ubuntu < 13.10 (which unfortunately includes 12.04 LTS we are using) use libedit 
2.11-20080614 while latest lldb source/Host/common/Editline.cpp relies on libedit 3.1 API (available only for 13.10).

I presume that Ubuntu < 13.10 builds should use their own libedit 3.1 probably linked statically, but I have absolutely no idea how to configure that.

Currently my build here fails:
