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
