Lightspark port and LLVM bug

[Rusty Nejdl]

I might be interested in taking over maintainership of this port but at 
present, this will not compile.  I have submitted a PR for an updated 
version of libxml++26 but also, the versions of LLVM (including -devel) 
both contain a bug that prevents this from compiling:

http://llvm.org/bugs/show_bug.cgi?id=9869

This suggests that I might be able to get it to compile using LLVM 
r131062.

Let me know your thoughts and once I get something working, I'll submit 
a PR.
