In binary distros usually you need to install the -dev version of the dependencies. For example, if you need libnet, the package called "libnet" will contain the precompiled library that will be needed at run-time, and the "libnet-dev" or "libnet-devel" (or something similar depending on the distro) will contain the header files that you will need to compile programs that will depend on libnet at runtime.

libnet is just an example, the same happens for the rest of similar packages.

i downloaded a libnet-devel rpm package tried to installed it.it said libnet has been alredy installed
