Hey all!

have a question to throw into the room :)

i'm just about to do -avuD world on a rather old (1 month) prefix. of
course as first step i had to do -v1 --nodeps portage to be able to do
anything. after that things went quite fine, up until
libxfce4util-4.4.3.

i get this problem (on interix, i guess hpux would have the same issue):

[stack trace partially omitted]
  File "/opt/gentoo/usr/lib/portage/pym/portage/dbapi/vartree.py", line
2580, in unmerge
    self._unmerge_pkgfiles(pkgfiles, others_in_slot)
  File "/opt/gentoo/usr/lib/portage/pym/portage/dbapi/vartree.py", line
2858, in _unmerge_pkgfiles
    unlink(obj, lstatobj)
  File "/opt/gentoo/usr/lib/portage/pym/portage/dbapi/vartree.py", line
2796, in unlink
    os.unlink(file_name)
OSError: [Errno 26] Text file busy:
'/opt/gentoo/usr/lib/libxfce4util.so.4.0.2'

scolling back a little through well-looking merge output, i stumbled
across this one:

...
>>> /opt/gentoo/usr/lib/libxfce4util.so.4 -> libxfce4util.so.4.1.1
>>> Safely unmerging already-installed instance...

Unable to do any operations on 'xfce-base/libxfce4util-4.4.3', since
it's EAPI is higher than this portage version's. Please upgrade to a
portage version that supports EAPI 'prefix 1'.

is this

 a) known?
 b) solvable?

thanks guys...

cheers, Markus
