I followed hivelogic article on how to install Ror and Lighttpd on Mac OS. > **[Dan Benjamin](https://danbenjamin.com)** > > Dan Benjamin's personal website. But I’m not sure I got Lighttpd in the right place. If I do “which lighttpd” and “lighttpd -v” I get answers from the terminal: /usr/local/sbin/lighttpd lighttpd-1.4.11 - a light and fast webserver But I can’t find a Lighttpd folder. Should there be one? How can I check so I got RubyGems, PCRE and FastCGI correctly installed? If I want to try installing again, can I just do that? Will it overwrite the files I already got installed? Or how do I uninstall? ---

Should there be one? No. You should see its source directory in the terminal application wherever you built it. Mine’s in /usr/local/src. But you won’t see the /usr directory in the Finder, because it’s Magically Rendered Invisible:-) > How can I check so I got RubyGems, PCRE and FastCGI correctly installed? Are they installed in /opt? If so, you can see that in the Finder. Look in /opt/local/lib/ruby and the various directories thereof. PCRE, on my machine, is in /usr/local/lib: ls /usr/local/lib/libpcre\* > If I want to try installing again, can I just do that? Will it overwrite > the files I already got installed? Or how do I uninstall? Yes, re-installing will replace the files that are being re-installed. –Al Evans ---

I know my way around a bit with the terminal but I’ve never compiled (is that the name?) an app myself. I got a Applescript making them visible 🙂 Either that or via the terminal. But that script is good to have. > > How can I check so I got RubyGems, PCRE and FastCGI correctly installed? > > Are they installed in /opt? If so, you can see that in the Finder.

Are both rubygems and fastcgi installed with their names, so I can make a find? > PCRE, on my machine, is in /usr/local/lib: ls /usr/local/lib/libpcre\* Got that. 🙂 > > If I want to try installing again, can I just do that?

I might give Lighttpd another chance. > –Al Evans ---

A find for -name ‘rubygems.rb’ should get rubygems; -name ‘fcgi.rb’ should find fastcgi. –Al Evans
