FrankenPHP plugin fails to build on FreeBSD

[gnomii]

Hi,

I am attempting to build the FrankenPHP plugin with the www/caddy-custom port using poudriere on FreeBSD, but the build fails due to a module path mismatch and subsequent build constraints issues.

Configuration used:

.if ${.CURDIR:M*/www/caddy-custom}
CADDY_CUSTOM_PLUGINS= github.com/php/frankenphp/caddy
.endif

Build error:

go: github.com/php/frankenphp/caddy@v1.12.1 found: parsing go.mod:
        module declares its path as: github.com/dunglas/frankenphp/caddy
                but was required as: github.com/php/frankenphp/caddy

This indicates that the module path has changed from github.com/php/frankenphp to github.com/dunglas/frankenphp, which breaks the build.

I then tried to switch to the new path:

CADDY_CUSTOM_PLUGINS= github.com/dunglas/frankenphp/caddy

Resulting error:

It seems there is a mismatch between the declared module path and the expected import path, and possibly an additional issue related to build constraints on FreeBSD.

Do you have any recommendation or known workaround to properly build FrankenPHP as a Caddy plugin on FreeBSD?

Thanks in advance for your help.

Follow the docs please. The internal/cpu error might reappear then, but we already have an open PR that will fix it.
