make test fails

My 'make test' is resulting in this: /usr/local/bin/nsgmls -i lang-en -D . -s ./dtds/dbxml-4.1.2/phpdocxml.dcl manual.xml /usr/local/bin/nsgmls:/usr/home/curt/cvs/php/phpdoc/en/preface.xml:50:4:E: general entity "contributors" not defined and no default entity /usr/local/bin/nsgmls:/usr/home/curt/cvs/php/phpdoc/en/appendices/filters.xml:282:19:X: reference to non-existent ID "zlib" *** Error code 1 looks like two issues but the zlib is stoping me from completeing the test.
