I've never had a need for PHP PEAR before, but recently someone programmed something for me that requires PEAR's Mail and Mail_Mime packages. Are these installed by Dreamhost? If not, am I able to install them myself somehow?
If you login to your shell, you can run the command:
This will list the PEAR packages installed on your server.see http://blog.dreamhosters.com/kbase/index.cgi?area=2990 for more details.
Also, if you find that you don't have the PEAR packages you want, you may have to compile and install your own custom PHP.see http://blog.dreamhosters.com/kbase/index.cgi?area=2538 for more details.
Hope this is of some help!
