There are two examples.  The ConfigStart/ConfigEnd code in mod_auth_dbm is

Uh, without -ldb it won't even link... you have to install db on solaris
boxes anyhow, since it's not there by default.  And when you do, -ldb
will work.

IMHO, this is the wrong way to do it.  All code regarding DB_LIB should
be moved to mod_auth_db.module.  I was hoping other folks would take care
of their own architectures after I did the Linux example.  I suspect
there's only three cases:  dbopen() is in libc, dbopen() is in libdb,
or dbopen() doesn't exist anywhere.  i.e. I don't even think there's a
need to do an architecture test.  It should be something like this:

    if ./helpers/TestCompile func dbopen; then
	if ./helpers/TestCompile lib db; then
	    LIBS="$LIBS -ldb"
	    if ./helpers/TestCompile func dbopen; then
		echo " + using -ldb for mod_auth_db"
		cat 1>&2 <<EOF
Unable to find dbopen()!  If you don't have db installed, then you'll have
to install it.  If it is installed, then it isn't in its default location,
and you'll have to specify the library directly via the EXTRA_LDFLAGS and
EXTRA_LIBS variables.
		exit 1

And similarly for mod_auth_dbm.
