Compiled PHP modules not matching what was configured

Question

When compiling php, I am removing pdo_sqlite, adding pdo_mysql and curl, but neither show up as modules once php is installed. Can anyone explain what's going on?

 ./configure \
    --with-apxs2=/usr/local/apache/bin/apxs \
    --with-mysql \
    --enable-force-cgi-redirect \
    --disable-cgi \
    --with-openssl \
    --with-mcrypt \
    --with-gd \
    --with-pdo-mysql \
    --without-sqlite \
    --without-sqlite3 \
    --enable-pdo \
    --without-pdo-sqlite \
    --with-zlib \
    --with-gettext \
    --with-gdbm \
    --enable-pcnlt \
    --with-curl

make && make clean && make install

After installation I run php -v and the built date confirms that php was just installed.

Here's the output to php -m
