it's a rather stupid argument, since it's easy enough to
test whether /usr/bin/perl exists and to set DEPEND
accordingly.
ADEPEND = $(AWK) -f $(TOPDIR)/scripts/depend.awk
PDEPEND = perl $(TOPDIR)/scripts/depend.pl
DEPEND := $(shell if [ -x /usr/bin/perl ]; then echo $(PDEPEND); \
else echo $(ADEPEND); fi)
Of course we should either set PERL = /usr/bin/perl or
make the test 'if [ -x `which perl` ]'.
