Re: LD_LIBRARY_PATH is not exported to subshells

Of course this works. But the problem is that LD_LIBRARY_PATH is part of 
the configuration of the run (shared libraries used in addition to the 
standard libraries). Of course I can write a script to edit .bashrc, but 
this is a ridiculed solution. Why cannot screen export the original 
LD_LIBRARY_PATH???
