net-print/hplip-3.13.5 needs to be edited so that it depends on virtual/python-imaging and not on dev-python/imaging as to resolve an hard block between pillow and imaging. Thanks.
This not possible until dev-python/reportlab also depends on the virtual. You can open a bug for reportlab, probably it already supports both implementations. If you do so please make this bug depend on the reportlab bug.
+ 09 Jun 2013; Daniel Pielmeier <billie@gentoo.org> hplip-3.13.5.ebuild: + Switch to virtual/python-imaging as hplip supports both pillow and imaging. + This fixes bug #472556. Thanks to Ivan Iraci for the report. Fixed in CVS.
