The package dev-util/bless calls scrollkeeper-update during its install phase. This is a sandbox violation, and aborts the ebuild. Another similar bug for a different package (with a patch to correct the problem) is described in 68287 http://bugs.gentoo.org/show_bug.cgi?id=68287 (I would try my hand at creating a similar patch, but that one is from 2004 and it sounds like there's some better way to deal with scrollkeeper)
Actually, there is a configure option to prevent this. According to bless-0.6.0/README.packaging: The only problem with this procedure is that Bless by default tries to register its documentation with Scrollkeeper (if it is found) during make install and unregister it during make uninstall. However this is not wanted on the packager`s system but on the user's system. To overcome this, Bless should be configured without scrollkeeper support by the packager: configure --without-scrollkeeper The attached diff works for me

Ok, I've added in --without-scrollkeeper to the ebuild. Note, I never had any problem with the scrollkeeper, so for reference it would be good if you could please post your "emerge --info". My guess is I won't be seeing the problem because I tend to use FEATURES="userpriv". The remaining lines in the patch (manually running scrollkeeper) shouldn't be necessary because they're handled by the gnome2 eclass. If you're still experiencing the problem, do please reopen this bug and I'll take another look at it. Thanks... 5:)
