Ok it appears that with a 64 bit Ubuntu VM, if I run
$ rvm reinstall jruby
it gets to:
jruby-1.7.2 - #importing default gemsets (/home/rogerdpack/.rvm/gemsets/), this may take time ...
then displays a crash dialog, which says
/lib/x86_64-linux-gnu/
ld-2.15.so has crashed, with details of:
The crashed program seems to use third-party or local libraries:
/home/rogerdpack/.rvm/rubies/jruby-1.7.2/lib/native/x86_64-SunOS/
libjffi-1.2.soIt is highly recommended to check if the problem persists without those first.
Do you want to continue the report process anyway?
Then it proceeds as normal and terminates, so at least it comes back, and seems to work after that.
With 32 bit Ubuntu VM, it appears to just hang forever (no dialog ever).
FWIW.
Thanks again.
