Error Rails - libxml-Ruby

I've been struggling with this error installing libxml-ruby while setting up my active merchant git. I've Googled all the components of the error many times, but I'm just not really sure what I'm looking at. There's a bunch of "no's" - anybody know how to interpret what I may be missing?

Building native extensions.  This could take a while...

checking for libxml/xmlversion.h in /opt/include/libxml2,/usr/local/include/libxml2,/usr/include/libxml2... no

Tells me you might be missing libxml2

Try to install it:

sudo apt-get install libxml2-dev

Well, as @TommyNicholas requested, I will try to explain why I zoomed in on libxml2 out of all others - it was a bit of a gut feeling, but I had some clues:

  1. It was the last line before the install declares failure, so that line has a lot of potential of being a critical error (the installation continues after the other failures...) it may not be the only one, but it deserves attention.
  2. The error message shows that it searched libxml2 under /opt/include/, /usr/local/include/ and usr/include/ - and didn't find it, so it stands to reason that it is not installed.
  3. A similar error is known to happen when installing Nokogiri, so it doesn't hurt to try the same solution.
  4. Anyway, if all else fail - RTFM - although my guess worked, the next step is to read the error message, which hints that there may be a more complete report in the logs - mkmg.log:

Check the mkmf.log file for more details.
