Portable Installation of `PyCall`, `Conda` and `PyPlot`

On its installation `PyCall`, `Conda` and `PyPlot` creates many files which embed absolute paths.
See https://github.com/JuliaPy/PyCall.jl/issues/767, https://github.com/JuliaPy/Conda.jl/issues/179, etc...
Also the file `qt.conf` on the `Conda` folder (Relates to `PyPlot`).

I wonder if:
1. The files will be written using relative paths instead of absolute paths.
2. In case (1) isn't achievable, could a function be added to `PyCall`, `Conda` and `PyPlot` to regenerate the files with the updated path?

Currently, the only option is to remove all of them, delete the folders (Including `Conda`), remove the precompilations files and reinstall.
