I'm sure it's fixable, it's just not the best first impression for those new to the ecosystem :) I love trying out new languages (prag pubs 7 languages in 7 days is great) but for production work I want to know that down the line if I need lib x, it won't be hard to find and even more importantly it will just work (or the googles machine will lead me in the right direction).

I actually stayed away from Scala for a while for this reason. SBT would blow up left and right. It's more mature now and with Play you can build performant web apps very quickly.
