Suddenly I get the error "cannot read termcap database"

Question

After switching from RVM to system ruby I keep getting this error. It doesn't seem to be affecting anything, but pops up when I try to install a gem or use irb. Any ideas on how to repair this? This is on Mac 10.7.

Answer 1

Found the answer here:

In Terminal I had to go to Preferences->Settings->Advanced, and change xterm-color256 to xterm-color.
