 details.

 Warning: the following items did not execute (for php5):
 org.macports.activate org.macports.configure org.macports.build
 org.macports.destroot org.macports.install
 Error: Status 1 encountered during processing.

 The libxml is happily installed, I checked with "sudo port install
 libxml", which ends up not installing it because the latest libxml already
 installed.  If I look at the config.log
 (/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_php5/work/php-5.3.0/config.log),
 I see at the end:

 ...
 configure:20354: /usr/bin/gcc-4.0 -o conftest -O2 -gstabs
 -fvisibility=hidden -I/opt/local/include -no-cpp-precomp -L/opt/local/lib
 -Wl,-rpath,/opt/local/lib -L/opt/local/lib conftest.c

          -lm  -lxml2 -lz -liconv -lm 1>&5
 configure: failed program was:
 #line 20343 "configure"
 #include "confdefs.h"


     char xmlInitParser();
     int main() {
       xmlInitParser();
       return 0;
     }

 Which will not work since the compile command is missing -lxml.  If I
 create conftest.c with the above content, and copy the confdefs.h from the
 directory of config.log, AND add the -lxml, the test compiles and links.
 If I leave out the -lxml, I get this error:

 Undefined symbols:
   "_xmlInitParser", referenced from:
       _main in ccGooSIo.o
 ld: symbol(s) not found
 collect2: ld returned 1 exit status

 So the configure test is missing -lxml?
