XML2 Libraries on Solaris

SUNWlxml sticks an ancient version of libxml2 in /usr/lib.

However the current version of the libxml2 package from sunfreeware.com is SMClxml2, which sticks libxml2 into /usr/local/lib.

libexec/libphp5.so looks for some XML functions that it expects to find in libxml2, which it can't until you change LD_LIBRARY_PATH.

In all fairness, this could just as easily have happened if you had used Linux instead of Solaris as your Web serving platform.
