That system* call won't do anything: export is a built-in in most shells
that sets an environment variable for the current shell session.
system* doesn't run the command you're giving it through a shell, so it
won't find `export`, and if you use system instead (which would run it
through a shell) it will only take effect during the (system ...) call,
after which the shell session is torn down.  You really need to use the
guile setenv if you want it to have any effect on started programs (or
use the spawn interface to specify env variables for a specific
invocation).

Best,
