 I couldn't upgrade from libxml2 2.6.31 to 2.6.32, and the reason is the
 "use_parallel_build yes" line that was added to the port in r36717. (I do
 have "buildmakejobs 2" in my macports.conf.) The build works fine, but the
 destroot phase doesn't:

 I had a [changeset:36613 similar problem with mysql5-devel] after adding
 "use_parallel_build yes" to it. Maybe a similar workaround can work for
 libxml2, until they fix it upstream.
