libiconv @1.14_0 install error - /usr/bin/tar: +CONTENTS: Not found in archive

[tjfulle@…]

Updated MacPorts today by

sudo port selfupdate
sudo port upgrade outdated

Upgrading outdated ports failed when installing libiconv @1.14_0 with the following error:

--->  Installing libiconv @1.14_0
Error: Target org.macports.install returned: /usr/bin/tar: +CONTENTS: Not found in archive
/usr/bin/tar: Error exit delayed from previous errors
Log for libiconv is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_textproc_libiconv/libiconv/main.log
Error: Unable to upgrade port: 1
To report a bug, see <http://guide.macports.org/#project.tickets>

I have tried the following to fix the problem

sudo rm /opt/local/var/macports/software/libiconv/libiconv-1.14_0.darwin_10.x86_64.tbz2
sudo port clean libiconv
sudo port install libiconv

and the problem persists. I am unable to update or install other ports because of this problem. Is there a way to bypass installing libiconv?

Relevant sections of the log file follow, the entire log file is attached.

System: Mac Pro 2 x 2.4 GHz Quad-Core Intel Xeon 6 GB 1066 MHz DDR3 Mac OSX 10.6.8 gcc version 4.2.1 (Apple Inc. build 5664)
