@aviks, both Conda.jl and PyCall.jl use `first(DEPOT_PATH)`. In particular, key preferences/paths are stored in `joinpath(first(DEPOT_PATH), "prefs", "PyCall")` and `abspath(first(DEPOT_PATH), "conda", "deps.jl")`

Weird. Someone reported this problem again just a couple weeks ago: https://discourse.julialang.org/t/error-building-pycall/16270/9

This isn't the correct fix because it only works for `@pywith` statements in global scope.

The right fix is probably to wrap the whole `try .. finally` in a `let exc=true` block.

cc @sethaxen since #879 is at issue here.

Impossible to reproduce since you don't provide the file…

I think we could use relative paths for things in .julia at least?

You can certainly re-run `build` for each package…it should re-generate the files if they have changed.

Can you give an example?
