I'm working on an ia64 box to develop a MySQL/Ruby app, and I'm
getting not very helpful SystemStackError traces:

/usr/lib/ruby/1.8/thread.rb:325: stack level too deep (SystemStackError)
        from /usr/lib/ruby/1.8/DBD/Mysql/Mysql.rb:34:in `require'
        from /usr/lib/ruby/1.8/DBD/Mysql/Mysql.rb:34
        from /usr/lib/ruby/1.8/dbi/dbi.rb:465:in `require'
        from /usr/lib/ruby/1.8/dbi/dbi.rb:465:in `load_driver'
        from /usr/lib/ruby/1.8/dbi/dbi.rb:459:in `each'
        from /usr/lib/ruby/1.8/dbi/dbi.rb:459:in `load_driver'
        from /usr/lib/ruby/1.8/dbi/dbi.rb:393:in `_get_full_driver'
        from /usr/lib/ruby/1.8/dbi/dbi.rb:373:in `connect'
         ... 19 levels...
        from /usr/lib/lts/cgi-bin/newplan:169:in `displayNewPlan'
        from /usr/lib/lts/cgi-bin/newplan:168:in `out'
        from /usr/lib/lts/cgi-bin/newplan:168:in `displayNewPlan'
        from /usr/lib/lts/cgi-bin/newplan:275

so far, my efforts to reproduce this in a simple testcase have failed,
possibly due to my ignorance of what those missing 19 levels are.  How
can I force ruby to display them?
