Description:
------------
I can't install pecl-memcached properly - after installation "php -v" outputs:
# php -v

All versions are up to date... php5_5.3.3_2, libmemcached-0.44, pecl-memcached-1.0.2

I've rebuilded php twice with "portupgrade -rf php5_5.3.3_2"
twice pecl-memcached and memcached database... also, reinstalled it with "make clean... deinstall... install"
nothing helps.

If I write "extension=memcached.so" before "extension=session.so" in extensions.ini, than I get:
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/20090626/memcached.so' - /usr/local/lib/php/20090626/memcached.so: Undefined symbol "php_session_create_id" in Unknown on line 0

and if after it... segmentation fault without core dump. I can't find any hints to fix the problem....
