Can I use PEAR on sites using the Ensim control panel?

Yes you can, but a change needs to be made to the php.ini file for your site.
The following line in /etc/php.ini
from:
include_path = ".:/php/includes:/usr/share/php"
to:
include_path = ".:/php/includes:/usr/share/php:/usr/share/pear"

If you have your own server the path to the above file for each site is:
/home/virtual/yoursitename.com/etc/php.ini
