configure.php failing

Hello, I'm trying to make some documentation changes and I've run into a problem with configure.php parsing manual.xml. Here's the output that I get when running php configure.php: Loading and parsing manual.xml... failed. ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:187:26) &language.types.boolean; --------------------------^ Entity 'language.types.boolean' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:188:26) &language.types.integer; --------------------------^ Entity 'language.types.integer' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:189:24) &language.types.float; ------------------------^ Entity 'language.types.float' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:190:25) &language.types.string; -------------------------^ Entity 'language.types.string' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:191:24) &language.types.array; ------------------------^ Entity 'language.types.array' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:192:25) &language.types.object; -------------------------^ Entity 'language.types.object' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:193:27) &language.types.resource; ---------------------------^ Entity 'language.types.resource' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:194:23) &language.types.null; -----------------------^ Entity 'language.types.null' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:195:31) &language.types.pseudo-types; -------------------------------^ Entity 'language.types.pseudo-types' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:196:32) &language.types.type-juggling; --------------------------------^ Entity 'language.types.type-juggling' not defined ERROR (/Volumes/secure/svn/phpdoc/en/language/types.xml:unknown) chunk is not well balanced Previous errors too severe. Stopping here. I'm running leopard and just did a fresh install of php 5.2.6. I'm not too familiar with language/types.xml but these lines have been in cvs for a while so I assume I might be the only one getting this. What should I be looking for to fix this? Thanks! -lucas
