The code screams PORTAGE_FETCH_CHECKSUM_TRY_MIRRORS to me which makes
it hard to read, I would suggest assigning it to a variable in advance
as to not have to repeat it this often. Some code snippets for ideas:

    key = "PORTAGE_FETCH_CHECKSUM_TRY_MIRRORS"

    v = int(settings.get(key), default)

    "!!! Variable %s contains non-integer value: '%s" % (key, ...)

If needed, add a word to key to make the variable name slightly more
meaningful; but avoid the full length if possible. eg. try_mirrors_key
