wappstack pear config

Using wappstack 5.4.9, PEAR is initially configured with a few directories as "c:\php\pear\<something>" which doesn't exist, and stopped me from installing additional PEAR packages.

eg: c:\\bitnami\\wappstack-5.4.9-0\\php> pear config-show

<snip>
PEAR data directory            data_dir         C:\\php\\pear\\data
PEAR test directory            test_dir         C:\\php\\pear\\tests
PEAR www files directory       www_dir          C:\\php\\pear\\www
<snip>

I just went through all affected dirs, and changed them like so: pear config-set data_dir C:\BitNami\wappstack-5.4.9-0\php\PEAR\data
