Lets see whether my knowledge is strong enough - if anyone has a better answer, I’m happy to be overriden. ;)

No separate package is needed. Here’s a setting to export the development versions (of everything):

    # Make an impure environment to support old-style deployments with
 <>    # traditional tools like pip, buildout, etc.
 <>    environment.pathsToLink = [ "/include" ];
 <>
 <>    environment.shellInit = ''
 <>    # help pip to find libz.so when building lxml
 <>    export LIBRARY_PATH=/var/run/current-system/sw/lib
 <>    # ditto for header files, e.g. sqlite
 <>    export C_INCLUDE_PATH=/var/run/current-system/sw/include:/var/run/current-system/sw/include/sasl
 <>   '';

Cheers,
Christian
