pear-Archive-Tar install failure

[erik@…]

MacPorts 2.0.3 on Mac OS 10.5.8 with Xcode 3.1.4 (Mac mini G4)

Steps to reproduce:
# port install pear-Archive-Tar

Expected result:
installed successfully

Actual result:
---> Computing dependencies for pear-Archive_Tar
---> Extracting pear-Archive_Tar
Error: Target org.macports.extract returned: shell command failed (see log for details)
Log for pear-Archive_Tar is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_php_pear-Archive_Tar/pear-Archive_Tar/main.log
Error: Status 1 encountered during processing.

lines 356-359 of the Log:

:info:extract package.xml
:info:extract tar: -: Not found in archive
:info:extract tar: Error exit delayed from previous errors
:info:extract shell command "tar -z -x -v -f '/opt/local/var/macports/distfiles/pear/Archive_Tar-1.3.7.tgz' - -C '/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_php_pear-Archive_Tar/pear-Archive_Tar/work/Archive_Tar-1.3.7/packagesource' package.xml" returned error 2

It appears there is a rogue dash character in the failing command?

I tried port clean and retry, same result.
