On 13 February 2002, Erik van der Meulen responded woefully:

Makefile.PL is a Perl script; "echo" is a shell command. See the
disconnect? However, Makefile.PL is a Perl script that glues together
bits of a makefile, and makefiles are just agglomerations of shell
code. (*shudder*) So you just need to put "echo $(CFCCFLAG)" in the
right spot in Makefile.PL. I suggest inserting it before line 111,
ie. apply this patch:
--- Makefile.PL.orig Wed Feb 13 09:20:46 2002
+++ Makefile.PL Wed Feb 13 09:20:03 2002

(Applying patches is another lesson. I hope it's fairly obvious which
line to add and where.)
However, I just tried this, and I don't think CFCCFLAGS is the problem --
I think CFLIBS is. Second version of Makefile.PL patch:
--- Makefile.PL.orig Wed Feb 13 09:20:46 2002

A bit of poking around shows that CFLIBS comes from $Config{libs}, and
you already showed us that when you ran "perl -V".
So, the first question once again: why does Perl's $Config{libs} include
-lndbm on a system that doesn't have libndbm installed?
Finally, it *doesn't matter* -- I bet that using Perl's linker flags for
spamc is unnecessary and irrelevant. So here's my third and final
Makefile.PL patch, which should fix the problem instead of just trying
to figure out what's wrong:

Craig, if you haven't already changed Makefile.PL like this, you might
want to consider it!
