contrib check fail at pgcrypto on Windows Server 2008 64bit 9.0dev (HEAD near alpha5)

Hi, all.

I built pgsql with following regulation (for buildfarm new entry).
- Windows Server 2008 64bit
- VC2005
- 9.0dev (HEAD near alpha5) 64bit

And I got a fail at "vcregress contribcheck" about only pgcrypto.
All CREATE FUNCTION of pgcrypto got ERROR.
(It passed "vcregress check")

STATEMENT: CREATE OR REPLACE FUNCTION decrypt_iv(bytea, bytea, bytea, text)
RETURNS bytea
AS '$libdir/pgcrypto', 'pg_decrypt_iv'
LANGUAGE C IMMUTABLE STRICT;
ERROR: could not load library "C:/Users/Administrator/mhome/pgsql-inst/lib/pgcrypto.dll": The specified module could not be found.

I tried LOAD command following:

test=# LOAD 'sslinfo.dll';
LOAD
test=# LOAD 'pgcrypto.dll';
ERROR: could not load library "C:/Users/Administrator/mhome/pgsql-inst/lib/pgcrypto.dll": The specified module could not be found.

I traced it with VC2005 debugger.
API "LoadLibrary" was called (and return NULL).
DLL's "DllMain" was not called in case of "pgcrypto.dll".

Is there any idea ?
