Hm strange I'm unable to install curl from Nixpkgs. This is the output

Doh! Here's it's using a curl from Nixpkgs, so if there is some problem with
resolving then that curl won't work. (OTOH, "download-using-manifests" uses
whatever curl Nix's configure script detected, probably /usr/bin/curl.)
In any case, you already have a curl:
/nix/store/ipqqrbwm3n9m15vny2kipx40pj25ahml-curl-7.16.2/bin/curl, you can do the
strace on that one.
(I don't quite understand why it would try to download the curl tarball
though...)
I attached the complete strace -- the part you mentioned looks like this:
