Hello, If you do an "svn up" it is going to fail. To solve that, delete the following two directories from your working copy: Pyrex Plex (These directories are at the same level as the one called "pypy".) Then do svn up again. The cause is that we switched to a new version of Pyrex and reorganized the repository to make it easier to switch to new versions in the future: Pyrex is now tracked in http://codespeak.net/svn/vendor/Pyrex/. It is copied from there and modified as needed for PyPy. See the svn commit message for details. As a result, the directory pypy/trunk/src/Pyrex, which used to be an external link, is now a real directory. Subversion doesn't realize the external link is gone before it tries to create the directory, and complains because a directory of the same name already exists in your working copy. Armin
