Huh? It's still an install-time dependency, and anyway the failure
would be pretty obvious. Please let us not spend time garnishing this
facility with unnecessary stuff, when the list of actually *important*
missing stuff is still a mile long. Think about what's needed to
support procedural languages as extensions, for starters. I'll give you
a hint: none of it has anything whatever to do with copying features
from RPM or Debian.
