I recently converted several machines to use CUPS.  On one of them,
which is running 3.0beta, I had to create a link to /usr/pkg/bin/lpr
from /emul/linux/usr/bin/lpr in order to print from acroread7.  On 
other machines, running 2.0.2 and -current -- releases that presumably 
straddle 3.0beta -- I did not have to do that.  What's going on?
