Seems you are using pre built Linux binary for fr24feed downloaded from respective site. Seems you built dump1090 from source code. Which version of dump1090 do you use (Malcolm Robb, Mutability, Flightaware)?
For Flightaware data feeder, there is no pre built x86 Linux binary or installation package available (except for RPi armv7). For x86 CentOS, you will have to build it using source code. I tried on Red Hat, but failed. As CentOS & Fedora are based on RedHat, this more or less applies to these also.
