I can competely fix this specific error instance with a one-line
config file change, but I don't want to end up in the same boat
again when some other program needs to be run during build time.
A more proactive workaround would be to treat "protocol not supported"
as a non-fatal error, just like "address family not supported" is.
Please let me know if this works in the build cluster. It will log
a warning but that should be justfied, because the system does have
an abnormal configuration.
