Deployment of a symfony app failed...Pear issue ?

Hi,

I installed (FTP) a Symfony (php5 framework) app on my dreamhost DreamHost account.

But I have 500 errors on each page that need to do some database accesses.

My mysql database is ok (I made a small database access php script to test that).


I was wondering if I have to install pear (using ssh for my account)
when I read this article (seen on the DreamHost wiki) :
http://herself.movielady.net/2007/07/13/installing-symfony-on-dreamhost/

So I tried to.

But, it bugs on step...2 of the article ($ pear install -o PEAR). I get this error messages :
"[crush]$ pear install -o PEAR
Did not download optional dependencies: pear/XML_RPC, use --alldeps to download automatically pear/PEAR can optionally use package "pear/XML_RPC" (version >= 1.4.0)

"

I tried the step I B 3 (from the same article) command ($ which pear, that is supposed to answer /home/naudjf/pear/pear.). But it displays:
/usr/local/php5/bin/pear
instead...

Well, I don't know what else to do. This pear thing is the only thing I am thinking about...

Thanx !!
