我正在使用yocto（版本为morty），我正在看一个我正在尝试为heimdal创建的配方问题（https://github.com/heimdal/heimdal）。在配置期间，它最终使用主机的perl安装而不是perl构建依赖项。所以它适用于任何有perl和安装模块的机器，但我不认为这是yocto应该如何工作（如果我错了，请纠正我）。
我的猜测是，这是Heimdal的configure.ac文件中的错误，或者是autotools的错误。我不是用autotools超级精明，想知道是否有人可以证实这一点？这是他们的configure.ac的直接链接
https://github.com/heimdal/heimdal/blob/master/configure.ac
当然，这也可能是我的食谱中的一个错误：

此外，我正在使用open-embedded（版本morty）默认perl配方和这个json-perl配方：
DESCRIPTION = "This module is a thin wrapper for JSON::XS-compatible modules with a few \
additional features. All the backend modules convert a Perl data structure \
to a JSON text as of RFC4627 (which we know is obsolete but we still stick \
to; see below for an option to support part of RFC7159) and vice versa. \
This module uses JSON::XS by default, and when JSON::XS is not available, \
this module falls back on JSON::PP, which is in the Perl core since 5.14. \
If JSON::PP is not available either, this module then falls back on \
JSON::backportPP (which is actually JSON::PP in a different .pm file) \
bundled in the same distribution as this module. You can also explicitly \
specify to use Cpanel::JSON::XS, a fork of JSON::XS by Reini Urban."
