After doing that, new error:
httpd: Syntax error on line 55 of /usr/local/apache28/conf/httpd.conf: API
module structure 'python_module' in file /usr/loc?
line 55 is:
55 LoadModule python_module modules/mod_python.so
I did reconfigure/compile to see if that helped, but here's the ls -la
2857 -rwxr-xr-x 1 root root 2911798 Apr 8 01:35 mod_python.so
