I have some webpages which use PEAR. I would like to install PEAR to my webspace but on installation I get some errors such as

CODE
FATAL ERROR! This directory exists, but we have no write permission in it.

You can grant this permission by logging on to the server and issuing the following command:
chmod 0777 /www/99k.org/g/o/o/goodideabadidea/htdocs/temp


Can I use PEAR and if so - how???

Thanks
