Hello,
I just imported lugaru and attempted to build it for rawhide, but it
failed in such a strange way on ppc64le, with errors saying it can't
convert bool to vectorized ints.

I fully expected lugaru to build properly on all architectures, as it
has nothing that makes it special in this regard. What's going on
here?
bool is a very special type on POWER because it's four bytes and not
just one byte, as on most other architectures. Related to this, the
compiler supplies a type __bool, and what I suspect is happening is that
a header included by the project contains
#define bool __bool
The most common source is <altivec.h> from GCC.
If you can't trace this locally, you can perhaps compile with
-D__altivec_bool_ret='()'
which should give you an error message with an #include stack, so that
you can see where <altivec.h> is included.
