Do you mean non-standard builds or forks of GnuPG, or alternative implementations of PGP? As it stands, the test suite is hardcoded to use gpg and gpgsm (see e.g. t/lib-gpg.sh). For normal use, the gpg.program and gpg.<format>.program config options can be used to override the programs to use. However, any alternative implementation would have to mimic the behavior of GnuPG (see gpg-interface.c -- a number of hardcoded arguments are passed in verify_signed_buffer() and sign_buffer(), and the output from various operations are GnuPG-specific.) -- hji
