Recently one of the ways to distribute packages(binary and source) is by using RPM. That’s all very good and everything but what to do if the rpms aren’t supported - as on osX? It gets a bit trickier but still manageable.

First grab the perl script - rpm2cpio.pl. Its usage is pretty straightforward

Thankfully, cpio is natively available on osx, so that’s pretty much it all amounts to.

There’s a handy tool for correcting data errors - Par2

The command line utility for linux is included in most packages, but alas not so on macos. There are still two ways to go - there is a port over at MacPorts but I already have Fink installed and I didn’t really want to get another clutter in the system. So I just found the ALT Linux Source, extracted the rpm and built it.

You can grab the source here Par2.tar.gz
Now just extract it and build it

Now you can just move par2 utility to your path directory of choice.
Just in case you don’t want to bother building it - grab the binary here - par2.bz2
