Segmentation fault when starting rails 3.0.9 console on OSX Lion under jruby

Trying to get my Ruby/Rails environment working on OSX Lion.

I am intermittently getting connection refused when trying to start irb or rails console.

I just rebooted the machine and got this when trying the rails console:

Chris-Kimptons-MacBook-Air-2:unicode-parallel-bug kimptoc$ rails c
[1]+  Segmentation fault: 11  ( JRUBY_OPTS='' jruby --ng-server 2>&1 > /dev/null )
Chris-Kimptons-MacBook-Air-2:unicode-parallel-bug kimptoc$ set | grep CC
CC=gcc-4.2

Any tips/tricks/suggestions for Jruby on OSX Lion?

It seems like it might be nailgun related. irb hangs, as per below. When I killed nailgun, it then just gives connection refused - presumably because its expecting nailgun.

I tried re-install jruby (using rvm) and it got past the above error with irb, but then "rails c" crashes, like so:

$ rails c
$ echo $?
227

Thanks in advance Chris


Solved it by re-installing jruby (possibly rvm too - sorry, cant remember now).

Probably partly related to nailgun issues- which should now be resolved.
