In my group, we typically set up software dependencies like this:

/libraries  
/gtk  
/2.4.11  
/rhel3  
/usr/  
/bin/  
/share  
/lib  
/irix  
# etc  
/gcc  
/3.3.1  
/bin  
#etc

So, we have libraries and utilities that we depend on installed to a  
separate directory, one directory for each different version and  
architecture. How can we do the same with Ruby and its libraries?  
I’d like to see something like:

/ruby  
/1.8.4  
/rhel3  
# ruby stuff  
/1.8.5  
/rhel3  
/irix  
# ruby stuff

/ruby-gnome2  
/0.14.1  
/rhel3  
/irix  
/0.15.1  
etc

/rmagick  
/1.0  
/2.0

So, each different Ruby library or gem would be installed to a  
different folder. Is that possible? By default, all the Ruby  
libraries and gems are installed inside the Ruby directory. And I  
think I’d prefer to keep them separate.

Any advice?

Thanks,  
Joe

Simpler question:

Ruby is installed in /foo. I want to install a Ruby library to /goo,  
and another Ruby library to /bar. How straight forward is that to set  
up? What flags to I need to give to each libraries setup.rb or  
exec\_conf.rb?

Thanks,

sudo ruby setup.rb install --prefix=“foo”

You’ll either need to symlink into the typical paths or add to the  
$LOAD\_PATH.

BTW, gems basically does this already, albiet foo-1.0.0/, Not usre  
about architecture though.

Also, I have a project that relates to this, so I’m wonder what you  
working on?
