gnupg-2.2.4: how to deal with failed tests

[Henry]

I finally got gnugp2 built without any fatal errors.
Most of the tests passed, but the following tests failed:
tests/openpgp/issue2346.scm
tests/openpgp/ssh-export.scm
tests/openpgp/export.scm
tests/openpgp/ecc.scm
tests/openpgp/armor.scm

I am not hip on using a binary that fails its tests.
Grateful for any advice on how to configure/build gnupg2 so that
it passes all its tests.

TIA

Henry
