try changing the order:


# start the compile in background in its own subshell
(cd /tmp/openswan* ; make programs >> $OUTPUT &)
dialog --backtitle "Compiling klips program" --tailbox $OUTPUT 15 45


the parentheses mean that the cd affects the make command, and *not* the
dialog and the rest of the script.


The '&' on the first line puts the make into the background, allowing
the script (and hence the dialog command) to continue.
