MacPorts headaches... follow-up

Some of these issues apparently have to do with the order in which things are done and may also depend on the fact that some of these packages require native C-language extensions.

I wanted to work with nokogiri to do some XML parsing. Given my previous post, I figured I'd better install this using MacPorts, which I did:

     sudo port install nokogiri

That was pretty straight-forward and worked quickly. However, when I went to irb to check things out, I got the following message:

irb(main):001:0> require 'nokogiri'

HI.  You're using libxml2 version 2.6.16 which is over 4 years old and has

plenty of bugs.  We suggest that for maximum HTML/XML parsing pleasure, you

upgrade your version of libxml2 and re-install nokogiri.  If you like using

libxml2 version 2.6.16, but don't like this warning, please define the constant

I_KNOW_I_AM_USING_AN_OLD_AND_BUGGY_VERSION_OF_LIBXML2 before requring nokogiri.

 

So I quit irb and installed libxml2

     sudo port install libxml2

which also went just fine.  Unfortunately, nokogiri still gave me that long warning message.

What I had to do was re-install nokogiri so that it would recognize the new version of libxml2 (which was now in the /opt/local tree) and then everything worked fine.

Seems like I can get things to work now, but having to remember previous dependencies and re-install packages to pick up those new items isn't going to be fun.
