* Description
When I attempt to emerge tuxonice-sources I encounter the following during the install phase:

>>> Installing (2 of 493) sys-kernel/tuxonice-sources-2.6.31

    if e[0]!=errno.EXDEV:
TypeError: 'OSError' object is not subscriptable

* Background
/usr/src is on a separate filesystem that is actually a bind mount to /usr/src

* Workaround
I do not know of any workaround at this time

* Resolution
I looked at the code only briefly, but it appears that the second exception is raised because "e" is an OSError-type object.  AFAIK it has no integral subscripts and the errno is retrieved through the "errno" attribute, e.g.:
 
(portage/__init__.py:7518)
    if e.errno!=errno.EXDEV:

Changing the line to above seems to fix the problem.
