The culprit seems to be the patch "fix ssh network tests so they work
in the test harness" from last March.

It adds the following line to ./harness/test.hs :

    cp "tests/network/sshlib" dir

This file copy is supposed to happen even if network tests are not
enabled in the test suite. Now why does it fail? It fails because the
file "tests/network/sshlib" is not listed in the "extra-source-files"
section of darcs.cabal!

I'm sending a fix right away.

The following patch sent by Guillaume Hoffmann <guillaumh@gmail.com> updated issue issue2507 with
status=resolved;resolvedin=2.12.0 HEAD

* resolve issue2507: add tests/network/sshlib to extra-sources-files

Thank you gh! darcs-2.12.2 has been accepted in stackage nightly-2016-09-08 
and can now be installed with "stack install --resolver=nightly darcs".
