The subject says it all: My emerge failed. I unchecked the mozaccess USE flag. My emerge succeeded. Thanks, and keep up the good work! Regards, Toon.
There is a warning about this in the ebuild itself - mozaccess and mozxmlterm are provided only as extras if they work. In other words, its mainly for development purposes that they're provided in the ebuild. Their functionality unfortunately can't be supported, because they're not supported upstream either. Best way to fix this is to remove 'mozaccess' from your USE flags. There are also some helpful forum posts on how to get it to build anyway.
