Use ${NIXPKGS_CONFIG} to enable or disable optional support for various
libraries:
gnupg =
{
ldap = true; // needs openldap
bzip2 = true; // needs libbzip2
usb = true; // needs libusb
curl = true; // needs curl
};
Per default, all options are enabled (which is what the expression used
to do prior to this patch).
Furthermore, there is the legacy option
gnupg =
{
idea = false;
};
for GnuPG version 1.x, which is disabled by default. GnuPG 2 ignores
this option.
