Local MacPorts build server no longer works

[Francisco Garcia]

Exploring the macports.conf man page I have noticed that:

archive_site_local is no longer listed
buildfromsource never is listed as an option, bit it is ignored. The
ports are still built from source in any case

Have these options changed (or been removed) in the latest releases?

I have a build server which used to work in the past, but now it no
longer works.
I do not think I have touched any configuration of the services
involved. The server in question
was working according this howto

https://trac.macports.org/wiki/howto/ShareArchives2

Now my client machine no longer fetches builds from my server. Instead
it just decides to build itself every port

In my macports.conf I have this line:

archive_site_local http://myserver.local/macports/

I have verified that the address is valid and provides an index of
/opt/local/var/macports/software (I am using Apache)

Also I verified that my keys (from pubkeys.conf) are the same in both servers

I am running out of ideas of what can be wrong and do not know how to
track down this problem. How should I debug this?

When I try to install a port already compiled by my server with the
"-d" parameter, there is no single reference to my
archive_site_local server in the output. Should I see my server listed
in the output?

thanks in advance!
