 Yes, and BTW it seems to have been necessary for me for the last couple
 of weeks/months, whereas in the "good old days" I never had to do a sudo
 ldconfig. I know this is a very vague statement, which is why I didn't
 report it, but could this be an indication of some problem, be it with
 gretl or with Ubuntu? 
I don't think it's a gretl thing (the need to invoke ldconfig 
explicitly before newly installed libraries are found by ld.so) -- 
and I think it's OK if you install libgretl into the main system 
location, /usr/lib, isn't it? (I experience the same thing with 
gnumeric, which I install in /opt/goffice.)
It seems to me too that "something changed" a while back (in the C 
library and ld.so? in libtool?) that has made a manual call to 
ldconfig necessary under conditions where it wasn't necessary
at one time. Not sure what.
