There is nothing we can do about file collisions between PEAR and its dependencies (Archive_Tar, Console_Getopt, and XML_RPC).
Sebastian: I don't know anything about this php stuff, but there should be no file collisions. Imho a way to fix this needs to be found sooner or later.
In order to install PEAR (dev-php/PEAR-PEAR), we need to bootstrap it. This bootstrapping requires the files from dev-php/PEAR-Archive_Tar, dev-php/PEAR-Console_Getopt, and dev-php/PEAR-XML_RPC to be present *before* they can be installed using the ebuilds. I see no resolution for this. *Maybe* we could change dev-php/PEAR-PEAR, dev-php/PEAR-Archive_Tar, dev-php/PEAR-Console_Getopt, and dev-php/PEAR-XML_RPC to not use the PEAR Installer (ie. not use the php-pear eclass). But this would, if it worked at all, be a very messy solution.
