> I think I can explain that: omalloc is written to work ''on top of''
another memory manager.
So, that is `--with-malloc=...`.
> There's an option that selects whether omalloc should offer the standard
'malloc/realloc/free' interface to its own allocators.
What does that mean? If one uses omalloc, why should one ''not'' want that
it offers `malloc/realloc/free`?
> There is also an option that selects how omalloc does its job: whether
it should do what it is designed for or whether it should just honour the
requests it receives by passing them on 1-1 to the underlying memory
allocator.
So, that's the option that we need, right? Is that `--with-emulate-
omalloc` that you added to spkg-install?
I guess I am now experiencing the same that you did: If `--with-emulate-
omalloc` is the ''only'' change, then installing the spkg fails with
