Getting started example doesn't work

[fsiler]

(clojurewerkz.titanium.graph/open (System/getProperty "java.io.tmpdir"))
IllegalArgumentException Need to specify a readable configuration file, but was given: /var...

So I tried:

clojurewerkz.titanium.graph/open {:storage.directory (System/getProperty "java.io.tmpdir")})

IllegalStateException Need to set configuration value: root.storage.backend  com.google.common.base.Preconditions.checkState (Preconditions.java:177)
user=> (clojurewerkz.titanium.graph/open {:storage.backend "local" :storage.directory (System/getProperty "java.io.tmpdir")})
ClassNotFoundException local  java.net.URLClassLoader.findClass (URLClassLoader.java:381)

user=> (clojurewerkz.titanium.graph/open {:storage.backend local :storage.directory (System/getProperty "java.io.tmpdir")})

CompilerException java.lang.RuntimeException: Unable to resolve symbol: local in this context, compiling:(NO_SOURCE_PATH:1:1) 
user=> (clojurewerkz.titanium.graph/open {:storage.backend :local :storage.directory (System/getProperty "java.io.tmpdir")})

ConversionException 'storage.backend' doesn't map to a String object  org.apache.commons.configuration.AbstractConfiguration.getString (AbstractConfiguration.java:1047)
user=> (clojurewerkz.titanium.graph/open {:storage.backend "berkeleyje" :storage.directory (System/getProperty "java.io.tmpdir")})

ClassNotFoundException com.thinkaurelius.titan.diskstorage.berkeleyje.BerkeleyJEStoreManager  java.net.URLClassLoader.findClass (URLClassLoader.java:381)

Does anyone have working code for this? I'm happy to submit the patch if so.
