It was my understanding that a package couldn't be unmasked in Gentoo without all of its dependancies being unmasked as well. Solution, keyword mask this version or stabilize setuptools ~0.6.6.
emerging dev-python/setuptools-0.6.6 and then dev-python/lxml-2.2.2 resolved the problem for me.
0.6c5 means 0.6_rc5. dev-python/setuptools-0.6.6 is already stable for some time.
