Setting up Groogle

Hello,

I'm trying to set up a tool called Groogle. It has a couple of dependencies that are not enabled by default in the servers.

These are:
PHP:
- GD (Default)

PEAR:
- Auth
- Log
- Text_Diff
- File_Archive

PECL:
- svn

The thing is I followed the Wiki's instructions on how to set up PEAR
packages (http://wiki.dreamhost.com/PEAR)

However when I got to the dependency check @
http://code.nextmedia.com.do/groogle/htdocs/ it still says they're not
installed.

When I try to install pecl svn I get:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to
allocate 92160 bytes) in /usr/local/lib/php/PEAR/PackageFile/v2.php on line
1288

It must be because it's trying to install on the default server location (not
allowed).

I believe I'm missing some steps. Any kind of guidance will be appreciated.
Thanks.
