In IPy-0.55, one of the tests failed. I submitted a patch to the author yesterday and he was nice enough to immediately release a bugfix version (i.e. ipy can be bumped to 0.56, but notice that this is no 0day bump request :P). However the test suite seems to import the already installed ipy, which causes the tests (which would normally work now) to fail if 0.55 is installed on the system. I'm rather new to python, so I don't know how to fix this, but I suppose somehow the import search path has to be altered. Otherwise the old ebuild seems to work just fine for 0.56, since not much changed except that little bug fix.
In portage. Thanks for contribution.
