>How-To-Repeat:
cd .../pkgsrc/net/wminet && bmake
>Fix:
Here are updates to patch-aa and patch-ab files that allow wminet to compile, 
install and run.

  Also, I had to use sudo to run wminet.  For some reason, wminet wouldn't open 
/dev/kmem even if I did a
 chgrp kmem wminet
 chmod 2555 wminet

Do I need to be in the kmem group on Darwin for this setguid to work?

Thanks.
