problem starting mysql5-server-devel 5.5.2 m2

[Puneet Kishor]

	$sudo port load mysql5-server-devel

	tail -f mumbai.geology.wisc.edu.err 
	120301 13:41:51 [ERROR] Failed to open log (file './mysql-bin.000018', errno 13)
	120301 13:41:51 [ERROR] Could not open log file

	120301 13:41:52 [Note] /opt/local/libexec/mysqld: Shutdown complete



I can't figure out where this log file setting is set. I can't find it in /opt/local/etc/my.cnf. 


Suggestions?
