it says,
Syntax Error on this two lines of those two files:
line 512 of /usr/local/apache/conf/httpd.conf
and
line 2 of /usr/local/apache/conf.d/rpaf.conf:
in those two files, on those two lines, your setup is looking for something (on those lines #512, and #2 respectively) that is not available/"could not be found"..
fix that, and it should work.
Possibly, all you may need to do is #, "comment out" those lines, or Add the area it cannot find.
Hope that helps.
Cheers
