well, that patch is supposed to fix stdenv on Darwin so that the platform can build packages depending on SWIG -- like Subversion, Git, etc. The re-build on Linux was due to the fact that the Perl builder script had to be modified to accomplish that. I guess I could have duplicated the builder script instead, applied the changes to the new one, say builder-darwin.sh, and then select builders in Nix by means of stdenv.system. This construct would achieve the same fix without causing a re-build on other platforms. However, introducing multiple builder scripts (that are mostly identical) strikes me as a particularly inelegant solution that complicates the Perl expression significantly. The expressions for 5.8 and 5.10 contain a lot of redundancy already -- I didn't want to complicate that even further. IMHO, there is a trade-off between short-term costs and long-term benefits at work here: * The simple patch is easier to maintain, but expensive in terms of re-builds performed now. * The complex patch doesn't cost anything now, but is harder to maintain in the long-term. Anyway, I would like to use nixpkgs-trunk on Darwin. For the time being, I'll just keep the necessary changes to my local repository until things have stabilized a bit. At that point, we can figure out how to merge them. It was probably a mistake to commit those changes to the central SVN repository right away. If I have inconvenienced anyone, then I am sorry.
