Is there any way to effect that calculation? I.e., in a normal build that calculation is based on the location of the executable, so virtualenv moves the executable to effect that. >> Does anyone know a way to get the normal effect on this Mac Python? > > You could copy the framework into the virtual python environment and > rewrite linker commands in the python command-line executable to use > that version of the framework. That sounds like the similar situation to the standard library on other posix systems, which I've avoided copying. To do that, I put a text file in that points to the original stdlib location, and in site.py I add that in (I only copy the portions of the stdlib that are needed when site.py is loaded -- os, re, etc). So the same thing should be possible with the framework, and that's not too much of a problem. I don't have any idea how to figure out the linker commands to change the Python command-line executable...? I don't even have the vocabulary to begin figuring that out, I'm afraid.
