You should "grep" nixpkgs for the error message. Then you'll understand
that not fetchurl yells about the achive type - its the unpackPhase of
the default build script.
You can disable it by
a) not using src env var
eg
mkDerivation {
installPhase = ''
ensureDir $out/bi
cp ${fetchurl{ ...}} $out/bin
chmod +x $out/bin
'';
}
Note that there are shortcuts like writeScript or runCommand or such.
b) overwriting it
unpackcPhase = ":";
c) overwrite phases
phases=" everyhting but unpackPhase";
I recommend a) or b)
