Was having problems logging in remotely. Had to go back and modify the blog-admin-url entries in all of my blogs except one. Not sure why the one was set properly though. Found the answer here.
This was really messing things up as I was also having trouble logging on locally due to the misconfiguration!
Also, had to modify httpd.conf to allow for xmlrpc though mod_jk!
<ifModule mod_jk.c>
/blojsom /Library/Tomcat/apache-tomcat-5.5.12/webapps/blojsom
JKWorkersFile /etc/httpd/workers.properties
JKLogFile /var/log/httpd/mod_jk.log
JKLogLevel error
JKMount /blojsom/* ajp13
</IfModule>
