Finally I was able to build and install the trunk version of nix.

I installed flex and bison (and perhaps other things that I can't remember now) and I run trough
make distclean
./configure
make

The build process seems to do most of the work.
I still have an error when the build process generates the documentation:

make[3]: Entering directory `/home/maggesi/nix/doc/manual'
/usr/bin/xmllint  --noout --nonet --xinclude --noxincludenode --relaxng /docbook-rng-missing/docbook.rng manual.xml
warning: failed to load external entity "/docbook-rng-missing/docbook.rng"
Relax-NG parser error : xmlRelaxNGParse: could not load /docbook-rng-missing/docbook.rng
Relax-NG schema /docbook-rng-missing/docbook.rng failed to compile
make[3]: *** [manual.is-valid] Error 5

I suppose that this depends on some missing packages but I'm not able to guess which one specifically is needed here. (I tried to install blindly several things related to docbook and the like but nothing work.)

Anyway I suppose that the build process did enough to produce a working executable so I did

sudo make install

then I used nix-env to install nix.
Now everything seems to work perfectly.
Thanks,
