RE: [Myexperiment-discuss] Detailed Installation Instructions for myExperiment

[David R Newman]

Hi Tony,

In answer to your first problem: I think the default behaviour of the gem 
commands between my system and yours is different.  The '-y' command is to 
install dependencies as well as the gem requested.  This is default 
behaviour for my gem command.  I will add it into the instructions as a 
catchall for those who gem command might work differently.

The could not find rails (= 1.2.6) is slightly odd, maybe the equals sign 
in the command is causing issues because it doesn't seem to be in the 
command specification (see http://www.rubygems.org/read/chapter/10#page33) 
but seems to work on some systems.  I will replace it with the command:

gem install rails --version 1.2.6 --include-dependencies

In answer to you second problem it is not unusual that the apt-get remove 
won't actually remove anything its just that it is common to have these 
packages installed and if you don't remove them there tends to be problems. 
However the problem you are having seems to be that libmagick9 isn't built 
properly for the OS version you are using. It might be worth trying a 
apt-get update and trying to install it again.  If that fails all I can 
suggest apt-get source libmagick9 and compiling it yourself.
