[Dovecot] sieve make test fails

I am trying out the sieve plugin (commit 843ba8e66e1b) and dovecot-2.0.rc2.

Given $ ./configure --with-dovecot=../dovecot-2.0.rc2/ --with-managesieve

make test fails with:

testuser@linode /tmp/dovecot-2-0-pigeonhole-843ba8e66e1b $ make test testsuite(testuser): Error: user testuser: Initialization failed: mail_location not set and autodetection failed: Mail storage autodetection failed with home=/home/testuser testsuite(testuser): Fatal: Invalid user settings. Refer to server log for more information. make: *** [tests/testsuite.svtest] Error 89

/home/testuser and /home/testuser/sieve exists. What am I missing?
