Hello,It seems that the openmpi mercurial mirror (https://bitbucket.org/ompiteam/ompi-svn-mirror) is not up to date with the svn reposiory. According to the history the last hg commit is dated from August 6th (svn r29008), contrary to the svn r29056 from yesterday.
Did something bad happened to the update process ?
Regards, Guillaume
