you must provide a source rpm.
Please look at the first answer in this thread:
FWIW, an updated src.rpm based on realcrypt 4.3 is available at:
http://home.arcor.de/doktor5000/RPMS/realcrypt-5.1a-2mud2008.1.i586.rpm
[...]
For this package I really don't want to have anything more to do with at as I only packaged it for the club ages ago and it takes time to rediff rebranding patches and test it.
After taking a closer look I honestly don't think I'll do it again, but it's pretty simple,, just dull...
If anyone wants to do it, go ahead, I'll answer any questions,, for myself I have zero interest, sorry..
I commented out all the rebranding patches, as there are no more additional tools
or kernel modules. I'll take a closer look, and try to do the hard work, if i'll have
some questions i'll come back to your offer.
