Summary of things:
- OS X Lion breaks our former version of the garbage collector.
- ECL now ships with two versions of that library: an unstable and a stable one.
- The unstable version is only used in OS X Lion.
- I had to make some changes to the unstable library recently.
- All patches have been committed and verified today. Nothing special is needed for building.
If you want to use LLVM (default in OS X Lion) just do as usual
If you want to use GCC change the first line to read
