When you submit a binary, all you're submitting to the qmaster is a path 
to that binary, and hence all that the qmaster passes on to the 
execution daemon is the path to the binary.  All the execution daemon 
will do is (more or less) fork and exec your binary path.  That means 
that the binary path must be resolvable on the execution host, and all 
shared libraries must be accessible and available from the shared 
library path (or run path).

You have multiple options for setting environment variables in your 
job's environment.  The first and most obvious is the submitting user's 
shell rc file(s).  Other favorites are the -V and -v switches.
