It looks like r.out.tiff was compiled using shared libraries (.so) which are
linked at run-time instead of static libraries (.a) that are linked at compile
time and make executables larger.  Either you're missing libjpeg.so.6 (in
which case, how did it compile?) or it can't be found in your LD_LIBRARY_PATH.

Places to check are /usr/lib, /usr/local/lib, or /opt/jpeg6/lib (a lot of this
is architecture dependent).  Once you find the directory, add it to your
LD_LIBRARY_PATH environment variable (should be set in your .cshrc or .bashrc
or .profile, depending on your shell) or if it isn't being set during login,
put a "setenv LD_LIBRARY_PATH /path/to/libjpeg.so.6" [csh, tcsh] or an
"export LD_LIBRARY_PATH=/path/to/libjpeg.so.6" [sh,ksh,bash] in the correct
shell startup file.
