[gentoo-user] profiling:/var/tmp/portage/xfce-base ... Cannot create directory

Hello!
  I noticed some strange messages in my ~/.xsession-errors log-file
today. They look like this:

profiling:/var/tmp/portage/xfce-base:Cannot create directory
profiling:/var/tmp/portage/xfce-base/xfce4-session-4.6.1-r1/work/xfce4-session-4.6.1/xfce4-session/xfce4_session-ice-layer.gcda:Skip
profiling:/var/tmp/portage/xfce-base:Cannot create directory
profiling:/var/tmp/portage/xfce-base/xfce4-session-4.6.1-r1/work/xfce4-session-4.6.1/xfce4-session/xfce4_session-main.gcda:Skip
. . .
and so on.

  I haven't seen such messages before, that is why decided to ask here
about what they mean. It is also strange that they mention the
'/var/tmp/portage/' directory. Maybe something is wrong with
installation system?

  Thanks.
    Vladimir
