Last night I downloaded the .tgz file of MOL 0.9.68, extracted, compiled 
and installed and it "just worked (TM)". I then tried a fresh extract, 
compile and install of 0.9.70 and had the same problem. Reinstalling 0.9.68 
got it working again. (NB I created separate /etc/mol-0.9.68 and 
/etc/mol-0.9.70 directories, with the appropriate one soft linked to 
/etc/mol before each installation.)

One curiosity: with 0.9.68 the sheep driver generates a system message 
"IP-filter: 192.168.52.11", which is the IP address I have set in MacOS. 
With 0.9.70 the message is "IP-filter: -64.-88.52.11". This suggests to me 
that the compilation of 0.9.70 is assuming plain chars are signed, and 
0.9.68 is assuming they're unsigned. Is this relevant?
