The environment variable LD_LIBRARY_PATH does not get set when one performs ssh 
with a command to be executed on the remote system, so that we get the 
following error message:

ssh 10.163.2.90 "get config scp /home/flr/test.txt"

get: error while loading shared libraries: libnvcore.so: cannot open shared 
object file: No such file or directory

The LD_LIBRARY_PATH described in /etc/profile does not get set when performing 
ssh with a command which is a problem that RedHat and other implementations 
have had. We see the environment variables that get created when an ssh with a 
command is offered by asking for set like this:

ssh 10.163.2.90 set
HOME='/home/flr'
IFS='
'
LOGNAME='flr'
PATH='/usr/local/bin:/usr/bin:/sbin:/bin'
PPID='27376'
PS1='\w \$ '
PS2='> '
PS4='+ '
PWD='/home/flr'
SHELL='/bin/sh'
USER='flr'

Now running ssh with no command so that we get a shell, the /etc/profile gets 
adopted, as does /home/flr/.profile :

ssh 10.163.2.90
$ set
FREDTEST='exported'
HISTFILE='/home/flr/.ash_history'
HOME='/home/flr'
IFS='
'
LD_LIBRARY_PATH='/usr/safetran/lib'
LOGNAME='flr'
PATH='/usr/local/bin:/usr/bin:/sbin:/bin:/usr/safetran/bin'
PPID='30760'
PS1='\w \$ '
PS2='> '
PS4='+ '
PWD='/home/flr'
SHELL='/bin/sh'
TERM='xterm'
USER='flr'
_='FREDTEST=exported'

So the only thing I can think of right now is to have a script called "get.sh" 
which sets environment variables as I need them which then executes get2 which 
is the executable that I created ? which seems like it's ugly.

Does anyone have a better solution? The dropping of environment variables when 
performing an ssh could very well be a security feature, but it seems to me to 
be a bug.
