Ferret Gem Install fails under Locomotive

Hi all,

Hoping somebody can shed some light on this for me, haven't been able
to find any posts anywhere about similar problems.

I was trying to install the ferret gem under locomotive. I opened the
terminal through locomotive so it had the correct paths set, and ran
"sudo gem install ferret". This is the error I received:

Building native extensions. This could take a while...
ERROR: While executing gem ... (Gem::Installer::ExtensionBuildError)
    ERROR: Failed to build gem native extension.

ruby extconf.rb install ferret
creating Makefile

sh: line 1: make: command not found

Gem files will remain installed in /Applications/Locomotive2/Bundles/
ferret-0.11.3 for inspection.
