Try adding CPPFLAGS and LDFLAGS to your configure command. They should
be able to prepend your path to the RPATH in the binaries, enabling
them to find your binaries before the ones in /usr/local/lib.
Assuming you have the full install of libxml and libxslt, you should
have both a 'lib' and an 'include' directory within your install path
(/usr/local/libxml2), the flags would be added to your command and
would look something like this:
CPPFLAGS="/usr/local/libxml2/include" \
LDFLAGS="-L/usr/local/libxml2/lib -Wl,-rpath,/usr/local/libxml2/lib" \
./configure \
--prefix=/usr/local/apache3 \
--with-apxs2=/usr/local/apache3/bin/apxs \
--with-curl \
--with-mysql=/usr \
--with-pdo-mysql=/usr \
--with-libxml-dir=/usr/local/libxml2 \
--with-xsl=/usr/local/libxml2 \
--enable-mbstring \
--with-mcrypt
You may have to read up on the LDFLAGS and CPPFLAGS to get them right
for your build.
