Hello,
AM_PATH_LIBGCRYPT uses gpgrt-config iff AM_PATH_GPG_ERROR is invoked first and sets $GPGRT_CONFIG. Otherwise it tries to use libgcrypt-config.
However libgcrypt-config is not installed by default anymore in master (as is already the case for the respective scripts for libksba et.al.) which will leave AM_PATH_LIBGCRYPT broken for projects using libgcrypt but not libgpg-error.
Is there some kind official guidance, should consumers of AM_PATH_LIBGCRYPT move to pkgconf or must AM_PATH_GPG_ERROR be used before AM_PATH_LIBGCRYPT?
Curently the AM_PATH macros of the gnupg projects behave differently, ksba, libassuan and libgcrypt require an explicit AM_PATH_GPG_ERROR while gpgme does not.
