PHP DP2 Compilation Error

I try to compile DP2 PHP extension on my system and got error:

couchbase/cluster.c -fPIC -DPIC -o .libs/cluster.o
/GITS/php-couchbase/cluster.c: In function ‘zim_Cluster___construct’:
//GITS/php-couchbase/cluster.c:119:24: error: ‘struct lcb_create_st3’ has no member named 'dsn’
create_options.v.v3.dsn = dsn;
^
make: *** [cluster.lo] Error 1

Ubuntu 14.04LTS
libcouchbase 2.4

Any one have this solution?
