Did you start from the git repo or from an RPM?

I would start from the git repo.  First install all the dependencies
by downloading the following file:

  http://pkgs.fedoraproject.org/cgit/libguestfs.git/plain/libguestfs.spec

and doing (as root):

  yum-builddep libguestfs.spec

You will have to comment out a handful of BuildRequires lines from the
spec file (because packages are not available in RHEL) until you get
everything possible installed.

Secondly, go to:

  http://oirase.annexia.org/tmp/libguestfs-RHEL-6.5/

and install augeas* and febootstrap* packages for your architecture.

Then clone the libguestfs upstream git from github, and follow the
`Building' section in the README file (all non-root).

You might need to do:

  make -C po-docs update-po

at some point half way through the build.  It should be obvious where.

Actually it's more accurate to say: follow the building
instructions here:

https://www.redhat.com/archives/libguestfs/2013-October/thread.html#00060

including creating localconfigure, localenv etc.

I just followed all that, and it certainly works for me.

Note you can run virt-builder without installing (and without needing
root) by doing:

  export VIRT_BUILDER_SOURCE=http://libguestfs.org/download/builder/index.asc
  ./run ./builder/virt-builder -l
  ./run ./builder/virt-builder fedora-19

Setting VIRT_BUILDER_SOURCE is necessary because the ./run script sets
the source to the local directory, which is useful for testing, not so
good for using.
