Philip-

I haven't seen a response to your question, so I'll take a stab.

I've only briefly looked at the sources, but a quick grep shows that build
host is a string returned by the function buildHost() in build/names.c,
and it's essentially

	gethostbyname(gethostname());

This leaves you a few options:

1) hack RPM's source code so that buildHost() returns what you want it
to return.  It's a trivial change.

2) If you don't want to hack RPM but you want it to get the build host
name wrong, many decent versions of UNIX and Linux support library
preloading, and using that method you can cause any program that is linked
shared (which RPM may not be, depending on your platform) to get a custom
version of whatever function you want to replace.  In this case, you could
write a custom `gethostname()' that just returns whatever you want it to
return and then compile that into a shared library and force it to be
loaded before the system libraries, so your version of gethostname() is
the one RPM sees.

3) Take maximum RPM's advice, and just build on a machine that has a name
you're not ashamed of.  ;-)
