Amarok 2 now operating in OS X

Yes, I finally got it working but not without some problems and some operational difficulties. Nevertheless, it is a huge step forward.
Yesterday, I had run into a problem with this guide as it asked for the xine-lib port file to be modified before installing. As a result it didn't install at all.
Today, I downloaded and installed Darwin ports and did the exact same
sudo port -d selfupdate # Didn't use the -d switch yesterday but this guide uses sudo.
Actually, it seems that Darwin ports and Macports are exactly the same.
In any event, without changing the port file at all, xine-lib compiled and installed without problem using

sudo port install xine-lib

I then ran into a problem with the Pre KDE requisites as neither Subversion, JPEG nor LIBMNG installed from ports.
I later got Subversion from here but despite several attempts I was unable to get either JPEG or LIBMNG installed so I went ahead without them.
So now I started compiling. It seemed to be going fine, but then after more than an hour, I got a message saying that I was about to run out of disk space. This is despite having had about 5 GB available at the start.
So, I ctrl-c'ed out, deleted iTunes Music (seems that iTunes actually copies the music which leads to a major duplication and unnecessary loss of disk space), KDE4 and Amarok stuff from the aborted install of Amarok 2.
Then I downloaded the Amarok2.dmg that I was pointed to in this thread and is available here.
This installed without problem and I was very quickly able to get Amarok 2 operating within OS X.
Importing my music collection was easy but two problems showed up:
1. Only .mp3 files play in Amarok 2 in OS X. No luck with .wma files despite the fact that Plex plays them without problem in OS X. So, I downloaded Flip4Mac from here but it made no difference. I posted in the same thread about this.
2. Other problem is that despite checking Last.FM in the Amarok Internet Preferences, no last.fm appears when I click the Internet tab (although everything else does). This really does sound like a bug.
