Is portupgrade working?

[walt]

I'm getting some funny errors from portupgrade.  Anyone else seeing
these?
# portupgrade XFree86-libraries-4.3.0_6
** Invalid package name: x11/XFree86-4-libraries: : Not in due form: 
<name>-<version>
** The following packages were not installed or upgraded (*:skipped / 
!:failed)
        ! x11/XFree86-4-libraries (XFree86-libraries-4.3.0_6) 
(invalid package name)

I get a similar error from imake-4, for example, but several other
packages upgraded without a problem.
