If a package is only supplied in autopackage format, you must not add
it to the tree. If a package is supplied in autopackage format and
some other sane standard format (for example a source tarball), use
the other format only.
Autopackage packages are totally unsuitable for Gentoo systems for a
large number of reasons:
To even unpack the package, you must run arbitrary code supplied by an untrusted source.
They install directly to the live filesystem.
Their intrinsic dependency resolver is broken.
They do not support the filesystem layout used by Gentoo.
They do not support configuration protection.
They can clobber arbitrary files on uninstall.
The linking mechanism used is insufficiently flexible.
The entire format is completely unportable and highly tied to x86
