Installed after install instructions:

git clone git://github.com/yiannist/llvm.git llvm
cd llvm/
./configure --enable-optimized --disable-assertions
make -j N (where *N* is the number of CPU cores you want to use for the compilation process)

Installing (changed sudo to su):

su
make install

Here should ErlangGC.so be located?

Sorry for that!

The truth is that this documentation is out-dated. In fact, you don't need custom LLVM (i.e., this repository) anymore. The necessary patches for ErLLVM have already been committed upstream and any vanilla LLVM version > 3.2 will work without any extra modifications. Thus, you just have to get a proper (vanilla) version of LLVM.

The GC plugin is now called "erlang" (not "erlang_gc").

Ι have to apologize for the misleading documentation, though.

These are good news! I'll try again the next days. Thanks.
