I am trying to install zend framework 2 using pyrus but i get a strange error on pyrus install : Pyrus\Config\Exception: Unable to parse invalid PEAR configuration at "."
 Pyrus\Config\Exception: Document is empty
  Pyrus\Config\Exception: Start tag expected, '<' not found
My config is :
<?xml version="1.0"?>
<pearconfig version="1.0">
     <default_channel>pear2.php.net</default_channel>
     <auto_discover>0</auto_discover>
     <http_proxy></http_proxy>
     <cache_dir>~/.pear/cache</cache_dir>
     <temp_dir>~/.pear/temp</temp_dir>
     <verbose>1</verbose>
     <preferred_state>stable</preferred_state>
     <umask>0022</umask>
     <cache_ttl>3600</cache_ttl>
     <my_pear_path>.</my_pear_path>
     <plugins_dir>/home/sebastian/.pear</plugins_dir>
</pearconfig>
Can someone help me figure out what is wrong with this ?
