--with-mm error

I install mm-library into /usr
(./configure --prefix=/usr)

I compile PHP4
./configure --with-apxs=/usr/local/apache/bin/apxs --with-mysql --enable-tra
ck-vars  --with-dbase --disable-debug --disable-pic --with-oci8 --with-oracl
e --enable-inline-optimization --disable-xml --with-mm=/usr


When I start Apache -

Cannot load /usr/local/apache/libexec/libphp4.so into server:
/usr/local/apache/libexec/libphp4.so: undefined symbol: mm_malloc
[FAILED]

Why?
