[Solved] Ruby - Gem bundle install no longer works

Question

Hi,
I am new to Linux, Arch and Ruby.
About 3 days ago I installed Arch on my virtualbox.
After I was happy with my installation (openbox as WM) I installed ruby.
I was able to install a project (Gemfile) using the command:
gem bundle install (from the terminal)
(That was after installing the bundle gem from within ruby: gem install bundle)
Today, after updating my Arch system, I had to install that project again (for reasons related to the project), and I cannot.
I write in the terminal:
gem bundle install
and get:
ERROR:  While executing gem ... (RuntimeError)
    Unknown command bundle
I searched the forums, but there's nothing relevant that I could find.
Can someone help?
Edit:
After more tries and searches I have found:
1. This has nothing to do with the Arch update as I feared.
2. The command to run is "bundle install" not as I initially did.
Apologies for cluttering the forum.

Hi mavenik,
Whilst it is not the best way to do it, the following worked for me
1) install gcc44 from AUR (you can probably use gcc45 too). If you are not sure how to do that please search the forums for installing from Aur or Aur wrappers (I use packer)
packer -S gcc44.
2) After it is installed temporarily rename your current gcc (4.7.x) 
sudo mv /usr/bin/gcc /usr/bin/gcc4.7
3) create a symlink to gcc4.4.x
sudo ln -s /opt/gcc-4.4/gcc /usr/bin/gcc
Test gcc version by doing
gcc --version
It should say 4.4.6 or similar
4) install ruby1.8 or ruby-enterprise from Aur (if this is required for redmine)
packer -S ruby-enterprise
ruby will now be compiled using an older version of gcc and gems will install correctly.
5) delete the symlink
sudo unlink /usr/bin/gcc
6) rename gcc4.7 back to gcc
sudo mv /usr/bin/gcc4.7
Test the version again to make sure it has reverted.
Please note the proper way to do this would be to set ruby1.8 / ruby-enterprise to compile with the older gcc by setting CC in the pkgbuild.
I'm not sure how to do that (had no luck) so the hacky solution above worked for me.
Please check each command above before you use it to make sure it is safe and valid for you.
Enjoy !
You should be able to compile with the older gcc by putting CC=/path/to/your/compiler right before "make", like so:
CC=/opt/gcc-4.4/gcc make
YEAH! I got it working!  Here's what I did: install "gcc45" from the AUR, then compile ruby-enterprise by downloading the AUR package and running:
CC=gcc-4.5 makepkg
... then install the package.  IT WORKS!
