problems on installing link-parser gem on snow leopard

Question

I cannot make link-parser gem working on my snow leopard.

When I tried to do 'sudo gem install linkparser' and I get:

Building native extensions.  This could take a while...
ERROR:  Error installing linkparser:
    ERROR: Failed to build gem native extension.

        /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

When I compiled link-grammar 4.3.5 from source (it went well) and then tried to do 'rake':

Don't know how to build task 'rdoc'

How to fix this? Is there any special compiling options I need to specify when I compile link-grammar?

It looks like you need to install pkg-config.

I'd recommend installing it by first installing XCode (if you haven't already), then Homebrew (a package manager for OS X), and then running brew install pkg-config in the terminal.

If you already have MacPorts or Fink installed I'm sure you can find the appropriate package in their repositories as well.

Thanks. I installed through macport. Then it complains the link-grammar version is too old. Then I downloaded the latest source (4.7.1) and compile it over again. It works~~~ neat!!! – lkahtz Feb 25 '11 at 05:44
Sure wish there was an easy way to do this in Windows. I really need linkparser gem, and I wish it didn't depend on pkg-config – Arcolye Sep 12 '11 at 08:43
