Thank you Steven and Ian for explaining how to use script or > to save the 
output of strace realplay.  I will try this soon but since I don't know 
how to interpret the output this will not get me very far.  (I am in BL3 
and strace and realplay are in BL2).

I was creating this sort of output when compiling lynx with help from Doug 
Kaufmann and never quite figured out what was going on.  I would send him 
the log files and be told what to do next (in my screwed-up system where 
we ended up compiling statically in order to make it work in the original 
BL2 even though I had updated glibc).   The error messages were not quite 
as cryptic there.
