MT plugin manager

I’ve had mt plugin manager installed for months and it’s worked fine but suddenly I’ve been getting this error-

Error in XML File:

not well-formed (invalid token) at line 4, column 10, byte 79 at /usr/lib/perl5/XML/ line 185

this was before I upgraded to MT 3.

considering this error is pointing to /usr/lib… I can’t help thinking this is a dreamhost problem.

Any ideas?
