BTT start problems on Mac OS X

[Mark Millikan]

I have downloaded the source snapshot of BTT
1. ./configure seems to like 'powerpc-apple-bsd' as machine type and  
completes
2. make local' completes with many warnings of unused variables
3. yaws -i works fine.

[m17:~] markmill% yaws -i
Erlang (BEAM) emulator version 5.4.3 [source]

Eshell V5.4.3  (abort with ^G)

4. btt -i aborts with:

[m17:~] markmill% btt -i

5. btt.conf is:

#
# Define where the Web server should be running
#
BTT_WWW_IP = 127.0.0.1
BTT_WWW_PORT = 8337

#
# Directory where all the WWW stuff is located
#
BTT_DOCROOT = /Users/markmillikan/btt_local_install/www

#
# Directory where the Database is located
#
BTT_DB_DIR = /Users/markmillikan/btt_local_install/db

#
# Directory where the received mails are stored
#
BTT_MAIL_DIR = /Users/markmillikan/btt_local_install/mail

#
# Directory where the logfiles are stored
#
#BTT_LOG_DIR = /Users/markmillikan/btt_local_install/logs/btt
BTT_LOG_DIR = /tmp

#
# Change the below if you want to use the command line interface.
#
BTT_ENABLE_CMD = no
BTT_CMD_IP = 127.0.0.1
BTT_CMD_PORT = 9338

Any hints as to how to proceed?
