New version of vobject is out. Could you please update the ebuild.
Created attachment 154911 [details] my version of ebuild for version 0.6.6 Here is my version on ebuild for version 0.6.6. The only change from ebuild for version 0.6.0 is location of the test script. Works for me, but I have python 2.5 installed.
vobject-0.6.6 is in CVS. Thanks for reporting :) Next time attach a diff against old ebuild instead of attaching an ebuild ;)
