NetBSD-current.

bash-3.2# /etc/rc.d/lighttpd start
Starting lighttpd.
2008-07-28 23:19:33: (plugin.c.205) /usr/pkg/lib/lighttpd/mod_indexfile.so: 
Trying to call undefined weak symbol `__register_frame_info'

bash-3.2# 

>How-To-Repeat:
install pkgsrc/www/lighttpd, and start it.

>Fix:
perhaps, /libexec/ld.elf_so changes affects this problem.

comment out below if-block at _rtld_find_symdef() function
in src/libexec/ld.elf_so/symbol.c, lighttpd can execute.

        /*         * If we found no definition and the reference is weak, treat 
the
         * symbol as having the value zero.
         */
        if (def == NULL && ELF_ST_BIND(ref->st_info) == STB_WEAK) {
/*
                if (in_plt) {
                        _rtld_error(
                            "%s: Trying to call undefined weak symbol `%s'",
                            refobj->path, name);
