Introduction
============

One of the most important lessons we learned about flux compactifications in the past couple of years is that moduli fields of the internal geometry can be stabilized in these compactifications (for a review and an extensive list of references see [@Grana:2005jc],[@dk:2006]). In a vast majority of the compactifications the addition of non-perturbative effects coming from gluino condensation or wrapped branes is needed in order to stabilize all the moduli. This is not totally unexpected [@dise] if one
