Problems with php5 + pear when upgrading to RELENG_6

[Julian Villan <villan@xxxxxxxxx>]

Im getting the following error when trying to do anything with pear or
pear modules:

# pear upgrade-all
/libexec/ld-elf.so.1: /usr/local/lib/php/20050922/xml.so: Undefined
symbol "XML_ParserCreate_MM"

I checked UPDATING and followed those steps, but that didnt change
anything. I did remove the version of pear and reinstall, also no go.
