It looks like a lot of the xpressive test fails come from missing files. See: *http://tinyurl.com/276jfw* eg. ../boost/xpressive/detail/static/compile.hpp:26:65: error: boost/xpressive/detail/static/productions/visitor.hpp: No such file or directory ../boost/xpressive/detail/static/compile.hpp:27:69: error: boost/xpressive/detail/static/productions/domain_tags.hpp: No such file or directory In file included from ../boost/xpressive/xpressive_static.hpp:24, from ../boost/xpressive/xpressive.hpp:18, from ../libs/xpressive/test/misc1.cpp:9: ../boost/xpressive/regex_primitives.hpp:24:69: error: boost/xpressive/detail/static/productions/productions.hpp: No such file or directory These three particular files are in svn release branch (and always seem to have been), but they're not all in the trunk. The fails are for the release branch apparently, so I'm not sure why they break. visitor.hpp is in the trunk, but is 'one directory up' (ie. cp visitor.hpp..), while the 'productions' dir isn't in the trunk at all.
