Okay, I tried on two of my target systems and I'm noticing a pattern.  When I
attempt to run the application without setting the LD_LIBRARY_PATH, the
application fail due to library incompatibilities which, is expected.  As soon
as I set LD_LIBRARY_PATH variable, every command executed in the shell fails
with a segmentation fault.  Something about the LD_LIBRARY_PATH environment
variable is causing problems.  Based on my reading, the dynamic linker checks
LD_LIBRARY_PATH first and then continues checking the linker cache so, setting
this variable shouldn't in my opinion cause all commands executed in the shell
to fail.  In case your curios, the two distributions I'm testing on are   
GuadaLinex and LinKat.  We're targeting a ton more but, I'm working with these
two until I can figure out how to get it to work on them

Thanks,
