it is super weird to attach to the object like this.  some might even say 
wrong.  move it into the class definition.

def getNonSystemArchiveDepends(fetchlist, eapi):
	...

	ARCHIVERS = {
		...
	}

regexes should always use raw strings.  there should also be a space after the 
colon in dicts.  so you want:

	re.compile(r'.*\.7[zZ]$'): 'app-arch/p7zip',

xz-utils, not lzma-utils

requiring people list gzip, tar, and bzip2 is a significant policy change 
(which i'm inclined to say is wrong).  it needs discussion on the dev mailing 
list first.

you don't need the \ there because you have paren already to gather things.

i know existing style doesn't follow it, but imo we should avoid string 
concatenation.  it makes the code harder to read imo.

	key = 'unpack.%s.missing' % mytype
	stats[key] += 1
	fails[key].append(...)

i would use "eapi_supports_xz_archives" unless there's a pre-existing style
