Yeah, thanks to some dubious "security" restrictions in macOS,
make check doesn't work unless you first do make install.
(Basically, they've lobotomized DYLD_LIBRARY_PATH, so that
the executables will only look for libraries in the configured
installation library directory :-(. It's far from clear to me
why that's of any security value when they still let you change
PATH, but I don't work there.)

This is documented in the macOS-specific installation notes.
