The last is the only one that will work for TLU, FYI, unless
gpg or gpg2 is in /usr/bin. I sanitize the PATH pretty
heavily, and no longer allow even /usr/local/bin due to ancient
broken stuff that users keep in it. TL_GNUPG env var should
work if you know how to make GUI processes inherit it.
Anyone who is interested in why I do this can read the comments
in TLMEnvironment.m.
