Problems installing mysql-gem


>Does anyone of you know this error?
I guess I do.

I bet you are on Ubuntu... Try this:

sudo apt-get install build-essential ruby1.8-dev

I am pretty sure you are missing at least one of these packages (According to the error, it seems ruby1.8-dev).

If this still does not help (but I am almost sure it will), just ping me, we will try to find out something.

Have a nice day,

Hi Peter.
