I tried to build DS9 using Nix, and managed to get something to build, although I'm not 100% convinced there's not a problem lurking somewhere (in large part because I am not a nix expert).

The main issue is that nix doesn't have things in /usr/ or /lib/ or /bin/ or ..., so it's a good way of finding out where some hard-coded assumptions are (e.g. by accidentally using a package in /usr/lib/ that you weren't expecting)
The changes I made include the following - I don't expect these are the best or sensible ways to do it, rather that they point to areas that we can possibly improve:
a) libxml2/xslt
It looks like tclxml isn't using pkg-config to find libxml/xslt
https://github.com/DougBurke/nix-astro-experiments/blob/master/ds9/nix-build.patch
I also had to replace /usr/include/libxml2 by the path to the libxml2 include directory (so probably pkg-config libxml2 --cflags or whatever it is) in tksao/configure
b) SSL
Somewhere there's a fall through that assumes the ssl directory is in one of the "standard" locations, which isn't the case here, so I had to set TLSFLAGS before the configure phase - e.g.
export TLSFLAGS="--with-ssl-dir=${openssl_1_0_2.dev}"
when ideally this would be picked up from pkg-config or a top-level configuration option (I forget now where this caused a problem)
