Quick answer:
I've now tested the pkgsrc rails setup and the only weak spot seems to 
be the missing "node" package. So the TODO list should consist only of 
the point "promoting wip/node to lang/node".

Details:
My setup: fresh install of NetBSD-6.0 xen amd64 domU without x-sets,
# env 
PKG_PATH=ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/6.0/All 
pkg_add pkgin
# echo "ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/6.0/All"; > 
/usr/pkg/etc/pkgin/repositories.conf
# pkgin update; pkgin install ruby193-rails-3.2.8; pkgin install 
ruby-1.9.3p194nb1

At this point it is already possible to use the rails software, the 
javascript runtime is only needed if you want to use the relevant 
features of rails. Moreover, pkgsrc includes the SpiderMonkey package 
(lang/spidermonkey), which provides the needed runtime. It is not 
autodetected (see 
https://github.com/sstephenson/execjs/blob/master/lib/execjs/runtimes.rb 
for details - it is marked as deprecated), but you can use it by setting 
the EXECJS_RUNTIME environment variable to "SpiderMonkey". The 
SpiderMonkey is good enough to work with the jQuery 1.8.2 javascript 
files, which come with rails 3.2.8. I had to install the wip/node in the 
past because SpiderMonkey was not able to work with some other 
javascript scripts. That (and the fact, that it is not autodetected, 
because it is marked as deprecated) leads me to the recommendation 
regarding the wip/node package.

FYI, my testing went on with the following steps:
Create a rails project "myproject":
$ env GEM_HOME="~/gems" rails new myproject
$ cd myproject
Test the javascript runtime:
$ env GEM_HOME="~/gems" PATH="~/gems/bin:$PATH" RAILS_ENV=production 
bundle exec rake assets:precompile
- fails
# pkgin install spidermonkey
$ env EXECJS_RUNTIME=SpiderMonkey GEM_HOME="~/gems" 
PATH="~/gems/bin:$PATH" RAILS_ENV=production bundle exec rake 
assets:precompile
- success, the file public/assets/application.js is compressed.

Feel free to ask if there is anything unclear. I don't use the rails 
packages from pkgsrc myself, maybe the author of the packages can also 
eventually provide additional information.

I am currently using some older version of wip/node (nodejs-0.4.7), I 
didn't test if the current wip package works with NetBSD - Dima 
mentioned in the original thread, that it needs some tweaking.
