I run boost on Windows but the first things to check should be similar:

1. Does apt-get get the compiled version of boost or just get the
sources ? Are the compiled shared and lib files there ?
2. In case the files are there, is the directory included in the
search path for the linker ?

Best regards,
Mau.
