This is a curious error.
It seems that the file "._printfw.h" (and others) was added to the archive, but at extract time, it couldn't be found.
Files whose names begin with "._" are created by OS X when a file with extended attributes is created on a filesystem that does not support extended attributes.
Is the filesystem MacPorts is installed on formatted as HFS+ (Journaled), or as something else? Are there other volumes involved (for example, have you symlinked the build or software directories or other parts of the MacPorts prefix onto other volumes), and if so, how are those volumes formatted?
