Can I install the memcached PHP extension with PECL?

Question

I'm having trouble installing the "memcached" PHP extension from PECL, though I can successfully installed the "memcache" extension. (They are separate PHP extensions.)

For example, these commands work okay:

$ sudo pecl install memcache
$ sudo pecl install APC
$ sudo pecl install oauth

However, attempting to install memcached causes errors:

$ sudo pecl install memcached
...
ld: library not found for -lmemcached
collect2: ld returned 1 exit status
make: *** [memcached.la] Error 1
ERROR: `make' failed

I'm using pecl, memcached, and libmemcached from Mac Ports (macports.org) on a recent Intel Mac. The libmemcached libraries can be found in /opt/local:

/opt/local/include/libmemcached
/opt/local/include/libmemcached/libmemcached_config.h
/opt/local/lib/libmemcached.2.0.0.dylib
/opt/local/lib/libmemcached.2.dylib
/opt/local/lib/libmemcached.a
/opt/local/lib/libmemcached.dylib
/opt/local/lib/libmemcached.la

Any idea what I may be doing wrong?

Andrei Zmievski (developer of the memcached plugin) kindly answered my email request with the following instructions:

$ pecl download memcached
$ tar zxvf memcached-1.0.0.tgz (or whatever version downloads)
$ cd memcached-1.0.0
$ phpize
$ ./configure --with-libmemcached-dir=/opt/local
$ make
$ sudo make install

This worked perfectly.
