Here is what to do: 

- type: telnet unixs.cis.pitt.edu and log in 

Start downloading the files, unpacking, compiling - up the point where
things don't work (which is the call of "Stats"). From there, 

- copy the attached two files into the ngrams directory (Stats will be
replaced by my version)
- like in the instructions on the web, change the first line of
count-unigrams.pl (on unixs.cis, this is /usr/pitt/bin/perl)
- type: chmod +x count-unigrams.pl
- type: ./Stats corpora/GEN.EN genesis/out

... and then proceed as explained on your webpage. 

I hope that works! I have tested this on Solaris 2.6 - and it works
fine, Ilya tried it on the unixs machines, where it worked, and on his
PC version, where something went wrong.
