PGXML support for postgreSQL on Windows

XML2 is not included in the windows postgresql installer. So I googled and
downloaded a windows binary from http://www.u-moe.org/pgxml/.

I tried to install it:

C:\Program Files\PostgreSQL\8.1\bin>psql -U postgres -f
..\share\contrib\pgxml.sql

And get this error:

psql:../share/contrib/pgxml.sql:4: ERROR:  could not load library
"C:/Program Files/PostgreSQL/8.1/lib/pgxml.dll": The specified procedure
could not be found.

I'm running the latest version of postgresql and windows 2000 and the
postgres windows user has all persmissions to your binary files.

Can somebody help me?
