Installation problem

I tried to install orgmk on a Windows 7 machine running Cygwin
according to the instructions at
https://github.com/fniessen/orgmk#sec-6-1.

Step 1:

I used

`git clone https://github.com/fniessen/orgmk.git`

instead of

`git clone git@github.com:fniessen/orgmk.git`

I got

`myname@mymachine /cygdrive/b/FQPath`
`$ git clone https://github.com/fniessen/orgmk.git`
`Cloning into 'orgmk'...`
`remote: Counting objects: 288, done.`
`remote: Total 288 (delta 0), reused 0 (delta 0), pack-reused 288`
`Receiving objects: 100% (288/288), 255.16 KiB | 343.00 KiB/s, done.`
`Resolving deltas: 100% (177/177), done.`

`myname@mymachine /cygdrive/b/FQPath`
`$ cd orgmk/`

`myname@mymachine /cygdrive/b/FQPath/orgmk`
`$ ls -l`
`total 240`
`-rw-rw-r--+ 1 myname Domain Users 1242 Feb 8 12:40 bigblow-pirilampo.setup`
`drwxrwxr-x+ 1 myname Domain Users 0 Feb 8 12:40 bin`
`drwxrwxr-x+ 1 myname Domain Users 0 Feb 8 12:40 lisp`
`-rw-rw-r--+ 1 myname Domain Users 2740 Feb 8 12:40 Makefile`
`-rw-rw-r--+ 1 myname Domain Users 132327 Feb 8 12:40 README.html`
`-rw-rw-r--+ 1 myname Domain Users 51379 Feb 8 12:40 README.md`
`-rw-rw-r--+ 1 myname Domain Users 43795 Feb 8 12:40 README.org`
`drwxrwxr-x+ 1 myname Domain Users 0 Feb 8 12:40 site-lisp`

Step 2:

I ran make:

`myname@mymachine /cygdrive/b/FQPath/orgmk`
`$ make`
`sh-4.4$ ls -l`
`sh-4.4$ type make`
`sh-4.4$ locate make`
`sh-4.4$ which make`

At that point, I seem to have a shell running that didn't pick up my
account name or pwd. As you can see, many commands now return
nothing, which I presume means they are aliases that are currently
undefined.

If I try to close the Cygwin terminal window, I see that three
processes are running on this TTY: /usr/bin/bash,
/cygdrive/c/Rtools/bin/make, and /usr/bin/sh. make's PPID points to
bash, and sh's parent has a PPID of 1. I'm suspicious of Rtools, but
I figure it's just make, and, if that were a problem, no doubt others
would have found it by now.

Do you have any suggestions as to what happened or how to finish the installation?
