postgres.exe - Entry point not found (PostgreSQL 8.3 devel)

Hello,

I have compiled PostgreSQL 8.3devel using Microsoft Visual C++ 2005 but when
I tried to start it (either by using the initdb.exe or postgres.exe) I
receive the following error message:

Message title: "postgres.exe - Entry point not found"
Message body: "It wasn't possible to find the entry point of the
xmlNewValidCtxt procedure in the libxml2.dll dynamic link library"

However, everything compiled well and without errors (only some warning).

I would be grateful if someone could enlight me on this one.

Marcelo.
