I had a couple of problems installing Jruby/Rails on Ubuntu. Here's what I had to change:

1) $JRUBY_HOME/bin/gem line 1, remove: 

' -J-Xmx512M'

2) Install gem 'jruby-openssl'.

3) $JRUBY_HOME/bin/rails line 1 add: 

"/usr/bin/env "

after the !.

4) Add this line to database.yml: 

 'host: localhost'

thread.so load error trying to install rails for jruby

Environment: Ubuntu Gusty. Already have ruby (1.8.6) and rails installed. Installed JRuby 1.1RC1, when running gems install rails -y --no-ri --no-rdoc, get this error:

thread.rb:35:in `require': No such file to load -- thread.so (LoadError) 

       from thread.rb:35
       from /home/fwu/apps/jruby-1.1RC1/lib/ruby/site_ruby/1.8/rubygems.rb:11:in `require'
       from /home/fwu/apps/jruby-1.1RC1/lib/ruby/site_ruby/1.8/rubygems.rb:11
       from :-1:in `require'
       from :-1

Newbie to Ruby and JRuby here. Any help is appreciated.

[Update] Solved. It must be some permission problem(s). I deleted exiting jruby installation, then unzip with gzip first, then decompressed the tar ball with tar -xpf command. Installation then worked with no problem. Originally I did tar -xzf with the downloaded .tar.gz file, could be that some permissions are messed up with that command.
