Odd. I've built parrot numerous times with /usr/ccs/bin/make and have
never seen this problem. There's even specific code in _set_make_c in
config/inter/make.pm to avoid it:
# RT#43171 this is an ugly hack
# replace the value for $(MAKE) with the actual path or we'll end up
# with a variable that recursively refers to itself
$make_c =~ s/\$\(MAKE\)/$prog/;
$conf->data->set( make_c => $make_c );
One way to reproduce this problem is to set an environment
variable named 'MAKE' to point to a program that is not in your $PATH.
For example (this is /bin/sh syntax; I don't recall the csh equivalent)
MAKE=/bin/bogus perl Configure.pl
will give the result you see. It's not at all clear to me what the author
of make.pm actually intended in such a case, so I'm hesitant to offer
a patch. Normally, I'd say a workaround would be to explicitly supply
a --make=/usr/ccs/bin/make argument on the Configure.pl command line,
but make.pm deliberately chooses to prefer the environment to a command
line option. Again, I don't know why, and it seems backwards to me,
but I'm reluctant to suggest changing it in case it was deliberate.
More generally, the default MAKE setting ought not to be recursive. I
really don't know why that variable is called MAKE instead of something
like MAKE_C. Using MAKE_C would eliminate the recursive issue without
the "ugly hack".
