The default installation of dt is setgid utmp.  If I export the
variable LD_LIBRARY_PATH before starting dt, the shells spawned by dt
don't have LD_LIBRARY_PATH in their environment.  If I remove the
setgid bit on dt, then the subshells DO see LD_LIBRARY_PATH.  One last
thing --- this only happens to LD_LIBRARY_PATH, not to any other
environment variable that I set.

What's going on??
