test suite failures in tofu.scm on 2.1.19

[Daniel Kahn Gillmor]

Hey all--

In trying to build 2.1.19 for debian, i'm seeing a test suite failure in
tofu.scm.

In particular:


0 dkg at alice:~/src/pkg-gnupg/gnupg2/build/tests/openpgp$ LC_ALL=C EXEEXT= PATH=../gpgscm:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/home/dkg/bin TMP=/tmp srcdir=/home/dkg/src/pkg-gnupg/gnupg2/build/../tests/openpgp objdir=/home/dkg/src/pkg-gnupg/gnupg2/build GPGSCM_PATH=/home/dkg/src/pkg-gnupg/gnupg2/build/../tests/gpgscm:/home/dkg/src/pkg-gnupg/gnupg2/build/../tests/openpgp /home/dkg/src/pkg-gnupg/gnupg2/build/tests/gpgscm/gpgscm  run-tests.scm  version.scm tofu.scm

So somehow it looks like the test suite is pulling from the system gpg
instead of the just-built gpg.


Wrapping the whole thing in strace to look at what calls to execve are
being done, i see:

1869  16:02:33.088593 execve("/home/dkg/src/pkg-gnupg/gnupg2/build/tools/gpgconf", ["gpgconf", "--build-prefix", "/home/dkg/src/pkg-gnupg/gnupg2/build", "--list-components"], [/* 54 vars */]) = 0 <0.000836>

1937  16:02:36.383087 execve("/home/dkg/src/pkg-gnupg/gnupg2/build/tools/gpgconf", ["gpgconf", "--create-socketdir"], [/* 55 vars */]) = 0 <0.000508>
1953  16:02:37.453386 execve("/home/dkg/src/pkg-gnupg/gnupg2/build/tools/gpgconf", ["gpgconf", "--change-options", "gpg"], [/* 55 vars */]) = 0 <0.000364>
1954  16:02:37.459441 execve("/usr/bin/gpg", ["gpg", "--gpgconf-list"], [/* 55 vars */]) = 0 <0.000298>
1955  16:02:37.505012 execve("/home/dkg/src/pkg-gnupg/gnupg2/build/tools/gpgconf", ["gpgconf", "--remove-socketdir"], [/* 55 vars */]) = 0 <0.000333>

So the final thing isn't invoking the right gpg, even though the first
ones are.

I'm not sure how to best debug this next.  Any pointers?
