 I'm running into a problem installing this gem.  I get the following error
 upon install:

 bash-3.2# port install rb-builder
 --->  Computing dependencies for rb-builder
 --->  Staging rb-builder into destroot
 Error: Target org.macports.destroot returned: shell command failed (see
 log for details)
 Log for rb-builder is at:
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports
 .org_release_ports_ruby_rb-builder/rb-builder/main.log
 Error: Status 1 encountered during processing.
 To report a bug, see <http://guide.macports.org/#project.tickets>

 I have the other ruby-related items installed:
 - ruby @1.8.7-p352_2+thread_hooks
 - rb-libxml2 @1.1.3_0
 - rb-rake @0.8.7_0
 - rb-rubygems @1.3.7_0

 I've installed this successfully on Snow Leopard and Lion, but it is
 failing consistently on several Leopard systems.  Any suggestions?
 Attached is the 'main.log' file.
