Compiling OpenGl

Hi

I've been reading the tutorials from the NeHe(http://nehe.gamedev.net/default.asp) Site (the opengl ones) and every one compiled perfectly untill I got to number 6. The tutorial was on texture mapping from bmp's but when I came to compile it (borland 5.5 - bcc55 -W texture.cpp) the compiler come up with an error at the bottom: error unresolved external 'auxDIBImageLoadA' referenced from c:\borland\mycode\texture.obj.
How am I supposed to fix it ? Am I doing something wrong or can't borland do texture mapping? If you know what i am supposed to change PLEASE help!!!!

Thanks
