The following command successfully installed Passenger on my cPanel 11 test machine:
Code:
APXS2=/usr/local/apache/bin/apxs PATH=$PATH:/usr/local/apache/bin ./bin/passenger-install-apache2-module
I installed from the source tarball. I'm not familiar with Rails or Ruby, so specific questions about those, I cannot help you with, sorry.
Info about the Apache install:
Code:
root@mundane [~/passenger-1.0.1]# /usr/local/apache/bin/httpd -v
Server version: Apache/2.2.8 (Unix)
Server built: Jan 23 2008 07:51:01
Cpanel::Easy::Apache v3.2.0 rev3691
Your Sys admin should be able to accomplish the above.
