n_barf trouble when compiling

[unitech]

I complied nebula with no errors and built a vs8 project file. I added all the directories and get this error during compile.

1>basic01.obj : error LNK2019: unresolved external symbol "void __cdecl n_barf(char const *,char const *,int)" (?n_barf@@YAXPBD0H@Z) referenced in function "public: __thiscall nList::~nList(void)" (??1nList@@QAE@XZ)

I tried the basuc01 and I get the same.  I cant find what lib this n_barf is in, nor can I on the net.

Coulld any one help?
