I just committed r191904, which should fix the tar problem
(actually, a libarchive problem) that caused this.

This problem was introduced in r191171 on 2009-04-16
when I went a little too far trying to eliminate some
duplicated code.  As a result, tar was no longer flushing
the pipe after it hit end-of-archive, which caused
gunzip to receive SIGPIPE for the final writes.
This only causes problems with /bin/csh, which reports
the exit status of the first command in a pipeline
(unlike /bin/sh, which reports the exit status of
the last command).
