than you would wont one dir for pure ruby gems and one for native
extensions e.g. i am not sure you want to do that inside gem. another
thing that works with ruby extension in general is to install native
extensions for multiple architectures into one directory tree. thats
something that doesnt work with gem either.

i think installing into VENDOR_HOME and symlinking back to the normal
location would be the better way. that way gem uninstall could just skip
all gems which are installed into the VENDOR_HOME dir.
openSUSE - SUSE Linux is my linux
openSUSE is good for you
