That's a likely possibility.  The "old" flag causes sup to replace
files that have changed on the server, but have an older datestamp than
the last time you supped.  I'm not quite sure how this could happen, but 
sup does seem to have synchronization problems with datestamps 
sometimes.  Perhaps you could have problems if you usually use one sup 
server, then switch to a different one, perhaps a sup server which is not 
getting the "delete" requests and has old files lying around (this would 
be a configuration error on the SUP server end).

One other likely possibility:  since you have the "keep" flag, perhaps 
you made some changes to these files (hacking them due to a previous 
buggy Makefile perhaps) and sup refused to write over them since you had 
modified them!  That's why I don't use the keep flag (I use "delete old", 
as per FreeBSD default sup examples), preferring to make a copy of my 
patches and change them manually so I don't "forget" that I've made them.
