I just installed the 0.5.3 gem on Leopard 10.5.2 yesterday and it still has the same problem -- but the solution described above doesn't work ...

On my system the gem is located here:

  /Library/Ruby/Gems/1.8/gems/libxml-ruby-0.5.3

The location of extconf.rb is here:

  ./ext/libxml/extconf.rb

Executing that file produces this error:

$ ruby ext/libxml/extconf.rb
checking for socket() in -lsocket... *** ext/libxml/extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.
