Dear Maintainer, * What led up to the situation? Running "./inst" showed: ./inst: line 123: AWK: unbound variable ### The variable AWK is used in several files, like "aux.sh", "inst.sh", "inst.sh.apollo", "nnstats.sh", "nnusage.sh", "prefix.c", and "upgrade_rc.sh". There is no test if it is defined or not. If it should be an environmental variable, it should be mentioned in the INSTALLATION file.
