Seems that the development of Cryopid has been revitalized recently, but
a new version has not been released yet.

Ok, thanks.  This worked.

However, I just released that I also have compile cryopid with the
headers of the same kernel version.

How can I specify this in the nix expression?

I tried the following (frankly, I do not understand very well what
I'm doing here)

   buildInputs = [zlibStatic kernelPackage_2_6_25];

but nix complains that kernelPackages_2_6_25 is an attribute instead
of a derivation (if I understand correctly the error message).

Thank you,
M.
