When hacking on a package without using cabal, you can

a) remove the problematic macro b) define it in the file yourself c) pass -D"MIN_VERSION_base(x,y,z)=1" on the command line

what about mimicking what cabal does, e.g. create a CPP file (e.g. 'cabal_macros.h') with the needed definitions and call ghc(i) something along the lines of

ghci -optP-include -optPcabal_macros.h TheModule.hs

We do a mixture of these things in lens. We set up #ifndef MIN_VERSION_foo #define MIN_VERSION_foo(x,y,z) 1 #endif guards for each MIN_VERSION_foo macro used within a model for development in case the user hasn't configured, and we set them to sensible defaults, (aka whatever works for me), and we have a .ghci file in the repository, that works once it has been configured and which helps support doctests and ghci users with: :set -isrc -idist/build/autogen -optP-include -optPdist/build/autogen/cabal_macros.h
