It will be a real pain in the butt to fix everything by hand because there are several parts to a mysql installation and they can be in different places in the system depending on how you installed it.
As long as your data folder is OK and is where mysqld expects it to be then everything that uses mysql should work fine. So I'd install a fresh copy using the installer from mysql.org
http://www.mysql.com/get/Downloads/M...ysql.orst.edu/
then just copy over your old data folder. it's not to hard to do this in the terminal
cp -r /path to old/mysql/data/ /path to new/mysql/data/
edit this to your setup of course.
the main things to look out for are the permissions on the data folder and data files.
No matter what you end up doing I'd download the installer and read the readme file. it has a lot of good info.
Have fun
