I can't install/run latest jruby using rvm on 64-bit Ubuntu (10.10)

rvm issue

using:
Linux desktop 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 02:41:37 UTC 2010 x86_64 GNU/Linux
rvm 1.2.0 by Wayne E. Seguin (wayneeseguin@gmail.com) [http://rvm.beginrescueend.com/]

I can build & install ruby-head just fine, but I really want jruby for some projects I have been working on another machine:

------
ruby-head 16:17 ~ $ rvm install jruby
jruby-1.5.6 - #fetching 
jruby-1.5.6 - #extracted to /home/david/.rvm/src/jruby-1.5.6 (already extracted)
Building Nailgun
jruby-1.5.6 - #installing to /home/david/.rvm/rubies/jruby-1.5.6
jruby-1.5.6 - #importing default gemsets (/home/david/.rvm/gemsets/)
Copying across included gems
execv failed: Permission denied (13)
ruby-head 16:18 ~ $
---

Hmm... failed to install cleanly, but I can switch to it, but none of the jruby commands work:

----
ruby-head 16:18 ~ $ rvm jruby
jruby-1.5.6 16:46 ~ $ jirb
execv failed: Permission denied (13)
jruby-1.5.6 16:47 ~ $ gem
execv failed: Permission denied (13)
jruby-1.5.6 16:47 ~ $ jruby
execv failed: Permission denied (13)
----

looking at the permissions for the /bin directory, it all looks peachy.  Any ideas?

---- ls -l /home/david/.rvm/rubies/jruby-1.5.6/bin/

Is this still a problem?

What we can't tell from the execv error message above is what file is giving you the EACCESS. Can you try strace -f jruby to see which file is actually giving you this error message?

No longer a problem. Using jruby 1.6.7 on either 64-bit or 32-bit java on ubuntu is working just fine.
