I build it very regularly, and there are several buildbots that also
build it continously (though they currently don't spam the mailing
lists).  For me, and the buildbots, head builds just fine with clang,
though.  What was the exact error you got during buildworld?

In any case, it is likely your problem is caused by my recent fixes to
rpcgen, which make it use the C preprocessor built during buildworld,
instead of always using /usr/bin/cpp.

What are your CC, CXX and CPP settings in make.conf?  And can you please
post the file:

  /usr/obj/usr/src/tmp/usr/include/rpc/rpcb_prot.h

which should have been generated by rpcgen during build.  It is probably
missing the line:

  typedef struct rp__list rpcblist;
