Since they provide DEB packages only, you have to convert the downloaded package to RPM before installing. You can easily do the conversion using the software alien:
Code:
alien --to-rpm bluepad_0.4_all.deb
maybe alien is not installed by default on your system, so first you have to search it using your usual package manager.
If you want or need to compile from source, well... it looks like they provide an already compiled binary executable (even if they call it source). Look at the Readme file inside the directory bluepad_0.4_complete_project_sources/bluepad_pc and just follow instructions (very short ones indeed).
