Version hell…I have the latest version of gems installed and gems -v proves this, but somewhere an old copy is hanging about - how do I get rid of this old version? This is driving me nuts! I seem to be getting conflicted installations of gems: For example $ ruby script/generate model product Rails requires RubyGems \>= 1.3.2 (you have 1.2.0). Please `gem update --system` and try again. brett@ubuntu:~/RoR/Apps/OpenBenefit/depot$ gem update --system ERROR: While executing gem … (RuntimeError) gem update --system is disabled on Debian. RubyGems can be updated using the official Debian repositories by aptitude or apt-get. brett@ubuntu:~/RoR/Apps/OpenBenefit/depot$ gem -v 1.3.5 ---

You installed Rubygems using apt-get which is… a very bad idea! You should NEVER do this :D. Just install rubygems using the source.

Now > its not working and I cannot re-install the mysql gems! it’s saying that you’re missing mkmf, which is part of the ruby standard library. Looks like this is part of the ruby-dev package on debian/ubuntu machines. Fred
