Without mentioning your config or anything about your build environment.

I assume the system you're building on doesn't have shadow password support in 
the standard header files?

With no indication of what the actual error message was...

Ok, by this I'm assuming you have passwd.c enabled in your config.  Do you 
have shadow password support enabled, and the built-in shadow support?

Well, mentioning what you're trying to do a little earlier in the message 
might help.

If you've got USE_BB_SHADOW set, then it shouldn't try to use the system 
shadow at all.  That's a bug.  Enabling USE_BB_SHADOW should _disable_ 
attempts to use the system shadow.h support, and provide replacements.

I'm guessing it doesn't?  Not having an environment in which to reproduce this 
at the moment, I'm not in a position to fix it without more information than 
you've given me...
