Thanks for tracking that down.  Does the following patch fix things
for you?

2005-10-30  Paul Eggert  <address@hidden>

        * lib/utimens.c (futimens) [HAVE_WORKING_UTIMES &&
        HAVE_FUTIMES]: Don't assume that futimes failing with errno ==
        EACCES means we must fail.  With /proc mounted, paranoid
        distributions like Mandrake 10.1 in high security mode don't
        allow ordinary users to read /proc, so futimes fails with
        errno == EACCES.  Problem reported by Theodoros
        V. Kalamatianos.
