[ruby-core:29491] [Bug #3138] Segmentation fault

Issue #3138 has been updated by Benedikt Eickhoff.


I'll do my best:

here's where I am and what I do:

cat /etc/issue

Ubuntu 8.04.3 LTS \n \l

installed some dependencies ...

sudo apt-get install zlib1g-dev libssl-dev libreadline5-dev libxml2-dev libsqlite3-dev

followed along this path, install ruby via rvm, setting ruby 1.9.1 as default ...
