Redmine

Hi all,
I am trying to install Redmine 3.1.0 on my MacBook Pro (Yosemite) and it works fine with webrick. Unfortunately when I try to set up passenger to run Redmine with Apache2, Apache does not run and showing this message:

httpd: Syntax error on line 499 of /opt/local/apache2/conf/httpd.conf: Syntax error on line 1 of /opt/local/apache2/conf/extra/mod_passenger.conf: Cannot load /Users/mickey9801/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/passenger-5.0.15/buildout/apache2/mod_passenger.so into server: dlopen(/Users/mickey9801/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/passenger-5.0.15/buildout/apache2/mod_passenger.so, 10): Symbol not found: _ap_log_error_\n Referenced from: /Users/mickey9801/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/passenger-5.0.15/buildout/apache2/mod_passenger.so\n Expected in: flat namespace\n in /Users/mickey9801/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/passenger-5.0.15/buildout/apache2/mod_passenger.so

I have googled to find anyone having same symptoms but seems that no one got "Symbol not found: ap_log_error" error.

./bin/about is as below
sh: darcs: command not found
sh: hg: command not found
sh: cvs: command not found
sh: bzr: command not found
Environment:

Environment production
Database adapter Mysql2
SCM:

Hope that anyone know the reason here. Thank you.
