sudo port upgrade <port> fails to untar the archive (permissions problem)

[sicot@…]

Since I updated to macports 2.2.0, I am no longer able to upgrade the outdated ports. For instance

> sudo port upgrade bison

gives

--->  Computing dependencies for bison
--->  Fetching distfiles for bison
--->  Attempting to fetch bison-3.0.tar.xz from http://mirrors.ibiblio.org/gnu/ftp/gnu/bison
--->  Verifying checksums for bison
--->  Extracting bison
Error: org.macports.extract for port bison returned: command execution failed
Please see the log file for port bison for details:
    /Users/sicot/macports/var/macports/logs/_Volumes_DATA_Users_sicot_macports_var_macports_sources_www.macports.org_files_ports_devel_bison/bison/main.log
Error: Unable to upgrade port: 1
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets

The log file shows that there is a problem of permissions despite the sudo command (the full log is enclosed):

:debug:extract Executing command line:  cd "/Users/sicot/macports/var/macports/build/_Volumes_DATA_Users_sicot_macports_var_macports_sources_www.macports.org_files_ports_devel_bison/bison/work" && /Users/sicot/macports/bin/xz -dc '/Users/sicot/macports/var/macports/distfiles/bison/bison-3.0.tar.xz' | /usr/bin/gnutar --no-same-owner -xf -
:info:extract /usr/bin/gnutar: bison-3.0: Cannot mkdir: Operation not permitted
:info:extract /usr/bin/gnutar: bison-3.0/.prev-version: Cannot open: No such file or directory
...

When I run the command manually (with sudo), it works. It is like macports does not run the command with sudo permissions but when I intentionally run without sudo i get the expected error:

> port upgrade bison
Error: Insufficient privileges to write to MacPorts install prefix.

I did not installed macports in /opt/local because of HD partitioning made by my IT department. I don't know if it related. i run macos 10.7.5.
