Hi Aleix,

I don't know of a YAML parser for Guile, but if you look at my email posted 2/22 I have a Guile package called NYACC.  This includes a "FFI Helper" that can generate the Guile FFI code based on yaml.h from libyaml.   The API is going to be C-like but if you do some
work to paste something on the front you will have something, I think.

Below I have a demo program and the yaml.ffi file used to generate yaml.scm.
When executed, the demo program outputs the following:

$ guile demo1.scm
#<yaml_node_t* 0x56353bc4af80>

I am working on this a bit more.  This requires some second order programming (e.g., pointers used as vectors) so  don't kill yourself.  I'm looking into it more.
