Perhaps not understanding the OS X permissions model
In the log for the httpd:
[Wed Mar 23 09:18:07 2011] [error] [client ::1] (13)Permission denied: mod_rewrite: can't access text RewriteMap file /Users/benson/x/btweb/web_2_0/resources/metadata/us-redirct-map.txt
ls -l /Users/benson/x/btweb/web_2_0/resources/metadata/us-redirct-map.txt
-rwxrwxrwx 1 benson staff 74542 Mar 22 20:05 /Users/benson/x/btweb/web_2_0/resources/metadata/us-redirct-map.txt
So, the mode is 0777, everyone has access, but the httpd gets 'Permission denied'.
Using the finder and GetInfo I see that everyone has full access. What am I missing?
This is probably caused by the directories further up the tree (namely /Users/benson/) not having the execute bit set.
