You are going to get following error unless you make the changes:

io/libs/iovm/source/IoObject_inline.h:322: error: ‘always_inline’ function could not be inlined in call to ‘IoObject_rawGetSlot_’: recursive inlining

1. Install yajl

git clone https://github.com/lloyd/yajl.git

Without it, you are going to encounter following error:

Linking CXX shared library _build/dll/libIoObjcBridge.dylib
ld: library not found for -lIoYajl

2. Install libevent

git clone https://github.com/libevent/libevent.git
cd libevent; autoreconf -i
./configure;make;sudo make install

Without it, you will encounter following error:

Linking CXX shared library _build/dll/libIoObjcBridge.dylib
ld: library not found for -lIoSocket

3. Check if additional libraries are available on your system

In case you cloned Io from github, go into build directory and type "ccmake .." to check which library is not on your system.
If you feel like you'll need one one of them, go and install it.

4. You are good to go make install

You will want to use build.sh script found in the io directory, if you cloned Io from github.
Or you may refer to this page: http://en.wikibooks.org/wiki/Io_Programming/Beginner%27s_Guide/Getting_Started

5. Enjoy Io

Have fun.
