**************************
Prosody was unable to find luaexpat
This package can be obtained in the following ways:

        Source:           http://www.keplerproject.org/luaexpat/
        Debian/Ubuntu:    sudo apt-get install liblua5.1-expat0
        luarocks:         luarocks install luaexpat

luaexpat is required for Prosody to run, so we will now exit.

question: why does nix-env --xml output differ from the --json output?

i think that this might be a bug.






nix-env -f '<nixpkgs>' -qa nix --out-path -A nix --xml

======================== summary ==========================
i've made many attempts of getting pyqwt to work and here is my newest fail:
SystemError: dynamic module not initialized properly

what i did was:
- now using qwt-5.2 bundled with pyqwt-5.2.0 implementation (for qwt)
- BUT i'm actually not using qw5 from the ${pkgs.qwt} directory but also the bundled one (don't ask, didn't get it working)

so this incarnation of Qwt.so seems to be working in regards to:
- readelf -s Qwt.so
