Installing Ruby 1.9 on CentOS

$ sudo yum groupinstall 'Development Tools' $ sudo yum install readline-devel $ cd /usr/local/src $ wget $ tar xzvf ruby-1.9.2-p0.tar.gz $ cd ruby-1.9.2-p0 $ ./configure && make $ sudo make install
test the installations with
$ruby -v
ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux]
Now, just in case the source became unavailable I'm including it here:
If you're going to use Ruby for Genexus, the version 1.9.2 and above are NOT suported as this date, instead use the version 1.9.1


Updating AsteriskNOW 1.6 to 1.8

If you have installed freePBX version, fist you need to update it

# yum update

Once this is done, we’ll run a yum shell command

#yum shell

> remove asterisk16 asterisk16-core

> install asterisk18-core asterisk18

> ts solve

> ts run

Thats it !!
