_psycopg.vc9.x86.manifest

Hi
This is my first mail in this mailing list and it's a very primitive
question!
I'm trying to "pip install psycopg2" on my windows7 msvc9 machine and
it give me this:

.
.
.
running build_ext

C:\Program Files\Microsoft SDKs\Windows\v6.1\Bin\mt.exe -nologo
-manifest psycop
g\_psycopg.vc9.x86.manifest
-outputresource:build\lib.win32-2.6\psycopg2\_psycop
g.pyd;2

psycopg\_psycopg.vc9.x86.manifest : general error c1010070: Failed
to load and p
arse the manifest. The system cannot find the file specified.

error: command 'mt.exe' failed with exit status 31

Any idea what's wrong? is it my fault ?!
