 If you are on centos download and install a newer flex:
 ftp://mirrors.kernel.org/fedora/releases/9/Fedora/source/SRPMS/flex-2.5.35-1.fc9.src.rpm
 
-Install the following packages (centos: sudo yum install pkgname)
-pcre-devel, libevent-devel, gperf
+# For 'jls-grok' you will need grok installed.
+  Install the following packages (centos: sudo yum install pkgname)

+
+# TODO(sissel): use a grok release
 svn checkout http://semicomplete.googlecode.com/svn/grok
 cd grok
 make
 sudo make install
-cd ruby
-ruby extconf.rb
-make
-sudo make install
 
+# On Linux:
 Check your /etc/ld.so.conf, or /etc/ld.so.conf.d/* . 
-If not already set add /usr/local/lib
+If not already set add /usr/local/lib and run 'ldconfig' as root to update the

-# RUNNING PREREQUISITES
-You must have a STOMP-capable message broker running. StompServer works fine if
-you don't want to configure anything.
-
-# RUNNING INSTRUCTIONS
-cd into /opt/logstash
-You'll need to start stompserver.. From the command line: 'stompserver'
-Next start logstashd via 'ruby bin/logstashd.rb logstashd.yaml'
-In another window start up the agent via 
-'ruby bin/agent.redhat.rb localhost:61613'
-This assumes your system is redhat derivative (fedora, centos, etc..)
-You should see a bunch of traffic as 'agent' loads log data.
-
-Now search via:
-ruby bin/search.rb linux-syslog '*alsa*'
-ruby bin/search.rb httpd-access '*favicon.ico*'
-
-Note: All files will need access to /var/tmp/ruby-uuid so run all scripts
-as the same user..
-
-# RUNNING THE WEB INTERFACE
-cd web
-Then run 'merb'
-
-This requires you have 'merb' installed.
