If fpdb is installed using an ebuild for the very first time then fperms mysteriously fails marking the *.pyw files as executables. During a second
install from the ebuild fperms was working which is more mysterious. I have found notices about this behaviour of fperms but couldn't find a proper
solution. However simply replacing fperms with chmod just does the work done.
