I didn't change anything. This is rather new installation of Cygwin.
I have seen some postinstall script failures on a few packages but would
these be modifying the system-wide PATH variable?

Nope. Haven't changed anything about the PATH.
In a new Cygwin Bash shell:
 bash-4.1$ cd ~
 bash-4.1$ grep -ERHn "PATH *=" * .* --exclude-dir=".*"

I have not changed anything about PATH anywhere.

Yep, I see it. So why isn't it working?

That's what I thought.

No man pages.
How do you get the man page generated?
