DOM and libxml2

Hi ppl I have a problem configuring PHP to work with the libxml2 libraries from xmlsoft.org. I use apxs, mysql, no magic quotes and trans sid quite successfully, but as soon as I give the --with-dom parameter to the configurator I run into problems. I have tried installing libxml2 from the rpms and from source. In both instances I get the error : /usr/bin/ld: cannot find -lxml collect2: ld returned 1 exit status the path to my libxml2 library is included in my ld.so.conf and I even get the error when giving the excact path i.e. --with-dom=/usr/local/lib Can anybody help me?
