How hard is it to get to a PR 1?

...Here I go again with the PR stuff, but i'm starting to get a little worried. I know, people always say it doesn't really matter what that number is, but i only really care about it as a sign that i'm moving in the right direction. My site's been up since the start of April and is still a 0 only. Now...is that weird? I have a LOT of links--we needed to rebuild them fast when our original site was destroyed, we moved, aand we were unable to 301 to the new site. We are starting to rank...pretty well considering the site's young age, not great but I'm not expecting to get back to where we were after 5 years on the old site, in only 5 months on this new one. {Lately we've stagnated, but it could be worse.} But after transferring almost all our old links almost right away to the new site plus heaping on many more over almost 4 months, and not seeing any outright penalty incurred {I didn't know about any dangers of a sudden glut of links back when I did it, we just didn't want all those sites to sit there with a broken link while we got no traffic!} it just has me scratching my head that nothing's changed PR wise. Is something weird going on or is this normal? We have a lot of mid to high level links at this point and no they aren't all blog comments in fact very, very few are. Most are links that the owners placed willingly on their sites because they are also RPGs or related sites. Yeah we also got many small links too but doesn't everyone?
