no destroot

[Robert Broome]

I am trying to perform a routine "update outdated" on my Mac 10.6.8 installation. I have done this many times in the past.
This time:
Error: org.macports.install for port coreutils returned: no destroot found at: /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_sysutils_coreutils/coreutils/work/destroot
The message is correct:
ls -a /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_sysutils_coreutils/coreutils/work
./				../				.home/				.macports.coreutils.state	.tmp/


The log says:
:notice:install --->  Installing coreutils @8.23_1
:debug:install Can't run install on this port without elevated privileges. Escalating privileges back to root.
:debug:install euid changed to: 0. egid changed to: 0.

:debug:install Error code: NONE

What can I do to fix this? 

Thanks
