I got the same problem just yesterday:
How I solved:
First: if you installed Boost by source, make sure you are compiling it to right compiler toolset that you are using at netbeans. For instance, I tested it with MinGW @ Windows 8 Boost/MingW.
Second: In Netbeans (I used 7.4 version), I added the libraries I want by hand:
Project Properties > Linker > Libraries > Add Library > Select the .a files.
EDIT:
This link maybe be useful: undefined reference with boost when I try to compile
