Hi  Matz --

As you suspected,

    require "etc"

failed in a similar way:

# ruby
require 'etc'
-:1:in `require': Undefined symbol "_Init_etc" -
/usr/local/lib/ruby/1.6/i386-freebsdelf4.0/etc.so (LoadError)
        from -:1


Running "nm" on etc.so shows:

# nm /usr/local/lib/ruby/1.6/i386-freebsdelf4.0/etc.so
00000e78 T Init_etc
...

Note that there is no leading underscore in "Init_etc".  That looks
suspicious! I wish
I could be more helpful, but I'm not very familiar with Unix linking
conventions. Let
me know if I can provide any more info.
