It continues to amaze me how much you have in there.  Oh, and my times 
earlier were probably user time rather than wall time, for which I'll 
shiftily blame the difference between csh's time builtin and 
/usr/bin/time.  Redoing that:

portmaster -L | filterfu:  43.6
pkg_version -vl'<':        30.5
portversion -vl'<':         3.6
portmaster -L --index-only: 2.5

As a bonus, the last one is not only the fastest but provides more 
useful information.  Off to change my update script...
