 * could not read all eix cachefiles of /tmp/eix-remote.FS2plX9m/eix-caches.tbz2

Probably your eix cachefile was *not* updated successfully.
Unless the above messages suggest another cause or you specified a
wrong filename, the most likely cause of this is that the server uses
another eix version than you or produced broken data. Please inspect
        /tmp/eix-remote.FS2plX9m/eix-caches.tbz2
whether this is a valid *.tar.bz2 archive containing eix cachefiles
(if it has already been deleted, download it using fetch).
If this is not the case (but was freshly downloaded), please report a bug.
Note that the archive is *not* broken if only the cachefile format versions
differ: In that case only report a bug if the eix cachefile format versions
in the downloaded file are *older* than that of the most current ~x86 eix
version in the portage tree (but first retry after several days before
reporting such a bug to give the server maintainers a chance to upgrade
after a version bump of eix).
Conversely, if the downloaded versions are even newer than that supported by
your eix, you will have to upgrade to the most current ~x86 version of eix
to use eix-remote: This inconvenience cannot be avoided and is not a bug!
