PHP 4.1.0 Compiling on OS X

Hey all, So I'm experimenting trying to get PHP 4.1 running under MacOS 10.1.1, running the following for configure: ./configure --with-apxs2=/Volumes/ego/apache2/bin/apxs --enable-calendar --enable-ftp --with-gd --enable-mailparse --with-mysql --enable-trans-sid Getting through configure ok, but getting this on the make: /bin/sh /Users/whoughto/Desktop/src/php-4.1.0/libtool --silent --mode=compile cc -I. -I/Users/whoughto/Desktop/src/php-4.1.0/ext/standard -I/Users/whoughto/Desktop/src/php-4.1.0/main -I/Users/whoughto/Desktop/src/php-4.1.0 -I/Volumes/ego/apache2/include -I/Users/whoughto/Desktop/src/php-4.1.0/Zend -I/Users/whoughto/Desktop/src/php-4.1.0/ext/mysql/libmysql -I/Users/whoughto/Desktop/src/php-4.1.0/ext/xml/expat -traditional-cpp -I/Users/whoughto/Desktop/src/php-4.1.0/TSRM -DTHREAD=1 -g -O2 -DZTS -prefer-pic -c dl.c dl.c:212: conflicting types for `php_dl' dl.h:26: previous declaration of `php_dl' make[3]: *** [dl.lo] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all-recursive] Error 1 Anyone have ANY thoughts? I'm a bit lost now... Wes
