Hi.

instructions from hivelogic. After running the

sudo gem install mysql – --with-mysql-dir=/usr/local/mysql

I get the following error:

Thank you.

Hola,

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,
Peter

In that case, I’d install ruby and rubygems using Macports. It’s a snap
after that.
