rb-builder: destroot fails on Mac OS X 10.5.8

[kaltree@…]

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.

Note: I was successful in getting the gem installed, using the gem executable. I made sure I was using the executable stored at '/opt/local/bin/gem'. It did report an error installing the 'builder' gem, but this time it was during the ruby documentation generation. I'm curious if there is a bug in the port definition that reports an overall failure if any sub portion of the port script fails.

The relevant error from your log seems to be:

:info:destroot WARNING: builder-2.1.2 has an invalid nil value for @cert_chain
:info:destroot ERROR:  While generating documentation for builder-2.1.2
:info:destroot ... MESSAGE:   Unhandled special: Special: type=17, text="<!-- HI -->"

I'm not familiar with ruby though and I don't know what this means or what to do about it.
