hung updates in ports

[Eric Hill]

Hi, I was told on IRC (blakkheim at freenode#freebsd) to send an email here
about some persistent non-updating ports reported by portsnap. After
running portmaster -a without error, I still get these in my nightly
emails. Individual portmaster/portupgrade only reinstalls the current
versions:

dri-7.6.1_3,2                      <   needs updating (index has 9.1.7_3,2)
libGL-7.6.1_4                      <   needs updating (index has 9.1.7)
libdrm-2.4.17_1                    <   needs updating (index has 2.4.52)

This is on a 9.2-RELEASE-p4 box with WITHOUT_X11 set.

Regards,
Eric
