Uncaught exception 'CouchbaseLibcouchbaseException' with message 'Failed to create libcouchbase instance'

I've installed the repo using sudo wget -O/etc/yum.repos.d/couchbase.repo http://packages.couchbase.com/rpm/couchbase-centos62-x86_64.repo

Then I've installed the packages through yum

yum install -y libcouchbase2-libevent libcouchbase-devel

i've then called yum install pecl

everything seems to install fine, yet if I run the following php :

$cb = new Couchbase("", "admin", "password", "default");
$cb->set("a", 1);
$a = $cb->get("a");
echo $a;

I get the following :

PHP Fatal error: Uncaught exception 'CouchbaseLibcouchbaseException' with message 'Failed to create libcouchbase instance'

i've disabled selinux, rebooted the machine, but the problem still persists.

php reports the following

couchbase support => enabled
version => 1.1.4dp1
libcouchbase version => 2.1.3
json support => yes
fastlz support => yes
zlib support => yes
igbinary support => no

Directive => Local Value => Master Value
couchbase.compression_factor => 1.3 => 1.3
couchbase.compression_threshold => 2000 => 2000
couchbase.compressor => none => none
couchbase.config_cache => no value => no value
couchbase.durability_default_poll_interval => 100000 => 100000
couchbase.durability_default_timeout => 40000000 => 40000000
couchbase.instance.persistent => On => On
couchbase.restflush => On => On
couchbase.serializer => php => php
couchbase.view_timeout => 75 => 75

Any Ideas on how to resolve the issue? I've even tried a fresh install of centos 6.4 with just php and couchbase, and it still shows the error message.
