portupgrade problem

Hello,

I've got some ports that they need to be updated.
/usr/sbin/pkg_version -vIL=
bash-4.0.33_2                       <   needs updating (index has 4.0.35)
ezm3-1.1_2                          <   needs updating (index has 1.2_1)
libpthread-stubs-0.1                <   needs updating (index has 0.3)
lsof-4.83B,4                        <   needs updating (index has 4.83C,4)
tmux-1.0_1                          <   needs updating (index has 1.1)
vim-7.2.239                         <   needs updating (index has 7.2.299)


I try to use portupgrade in order to update my packages with:
portupgrade -rR vim-7.2.239 (for example)

But nothing happen and I've got the folowing return:
portupgrade -rR vim-7.2.239
[Gathering depends for editors/vim
.........................................................................................................
done]
[Exclude up-to-date packages ........................................ done]

It's really strange because for the package "bash" I use the way: make
deinstall && make install in the directory /usr/ports/shell/bash and all
works great ! and this confirm that my second update process was successfull
:

bash -version

The last version of bash is present on my system. It's seems that the INDEX
is corrupted but I try to ran pkgdb -F and it did nothing.

I try to make some search on the mailling list or google, there is some idea
(like ) but nothing solve my problem.
Someone have an idea to help me ? or some tips to check the consitency of my
index ?

Thanks in advance for yours helps (My FreeBSD version: FreeBSD 8.0-RC1)
