Yes, thanks for the hint.
I searched a bit for which configure option is with libyaml, but
completing option did not work.

So this method, as the first one works.

But, it seems the problem is even bigger.

I'm currently using rvm, and so I did: "rvm install ruby-head -C
--with-libyaml-dir=/opt/local"

Which apparently works, seeing the first line of config.log:
$ ./configure --prefix=/Users/benoitdaloze/.rvm/rubies/ruby-head
--with-libyaml-dir=/opt/local

But I still get:
Error running 'make -j 3', please check
/Users/benoitdaloze/.rvm/log/ruby-head/make*.log

The make error log just complains about libyaml, and not finding miniruby.

So I went myself in the src (.rvm/src/ruby-head)

And using 'make' it works.
But using 'make -j 3' I get the error.
(before each 'make' command I did a 'make clean')

I don't know much about the syntax of make,
but as far as I know '-j 3' was just to specify the number of
threads/processes gcc can use.

So here is the output of 'make' and the one of 'make -j 3':
