Dont worry about Google so much just yet. Just keep working on your blog and eventually you will get noticed by google. Google is actually the slowest at showing and updating Backlinks.
IMHO MSN is the fastest. If you look at your blog in MSN you will see you are listed with 21 backlinks (which isnt that much). But eventually you will get there.
Actually scratch that... I just tried MSN and my blog has 28, then i tried yahoo and my blog has 358 which is more like it :D. It must be that time of the month for MSN.
Checking yours livingjourney, it shows 204 backlinks so you are actually doing quite well. Just keep it up and you will get a PR to prove your efforts.
At the end of the day PR doesnt count for anything if you are getting visitors but its still nice to know you are being awarded for your effort with something.
